Chapter 4

10. Assume a JFET has the transconductance curve shown in Figure 4–76. (a) What is IDSS? (b) What is VGS(off)? (c) What is the transconductance at a drain current of 2.0 mA?

ID= 2.3 mA
VGs = -2 v
VD= Vpp – ID( RS+RD)
15 – 2.3m (1k +3.3 K)
15 – 2.3 (4.3 K)
VDS= 5.11 2.3 m * 1 k
Vs= 2.3 V

11. Assume the JFET with the transconductance curve shown in Figure 4–76 is connected in the circuit shown in Figure 4–77. (a) What is VS? (b) What is ID? (c) What is VDS?

VD = VDD - ID*RD = 15V - (2.1mA) (3.3k Ω) = 8.07V ID = IS 2.1mA VS = IS * RS = 2.1mA * 1k Ω 2.1V ID = IDSS ( 1- (VGS/VGSoff))2 6.4 ( 1 - ( -2.1 / -5 )2 2.1 mA VDS = VDD - ID(RD + RS) 15V - (2.1MA) ( 4.3k Ω ) 15V - 9.03 = 5.97V

13. For each circuit in Figure 4–78, determine VDS and VGS. VD = VDD – ID times RD
VS = IS times RS VDS = VDD - ID(RD + RS) VGS = VG - VS
a) VD = 12V - (1mA) (4.7k Ω) = 7.3V VS = (1mA) (1k Ω) = 1V VDS = 12V - (1mA)(5.7k Ω) = 6.3V VGS = 0V - 1V = -1V
b) VD = 9V - (3mA) (470 Ω) = 7.59V VS = (3mA) (100 Ω) = .3V VDS = 9V - (3mA)(570k Ω) = 7.29V VGS = 0V - .3V = -.3V
c) VD = -15V - (5mA) (2.2k Ω) = -26V VS = (5mA) (470 Ω) = 2.35V VGS = 0 - 2.35V = -2.35V

21. Each E-MOSFET in Figure 4–81 has a VGS(th) of +5 V or −5 V, depending on whether it is an n-channel or a p-channel device. Determine whether each MOSFET is on or off. A ) ON

#### Turn of the Screw

...home after the previous governess died. Douglas begins to read from the written record, and the story shifts to the governess’s point of view as she narrates her strange experience. The governess begins her story with her first day at Bly, the country home, where she meets Flora and a maid named Mrs. Grose. The governess is nervous but feels relieved by Flora’s beauty and charm. The next day she receives a letter from her employer, which contains a letter from Miles’s headmaster saying that Miles cannot return to school. The letter does not specify what Miles has done to deserve expulsion, and, alarmed, the governess questions Mrs. Grose about it. Mrs. Grose admits that Miles has on occasion been bad, but only in the ways boys ought to be. The governess is reassured as she drives to meet Miles. One evening, as the governess strolls around the grounds, she sees a strange man in a tower of the house and exchanges an intense stare with him. She says nothing to Mrs. Grose. Later, she catches the same man glaring into the dining-room window, and she rushes outside to investigate. The man is gone, and the governess looks into the window from outside. Her image in the window frightens Mrs. Grose, who has just walked into the room....

#### The Star

...character? To what extent is her final protest justified? How do the other characters portray themselves by their attitudes toward the ritual? Mrs. Tess Hutchinson stands out right from the start: she arrives at the lottery late. She explains to Mr. Summers that she was doing her dishes and forgot what day it was. The town treats her lateness lightly, but several people comment on it, “in voices just loud enough to be heard across the crowd, ‘Here comes your Missus, Hutchinson,’ and ‘ Bill, she made it after all.’” (Jackson 501). It is ironic that she is the one who wins the lottery, and is fated to be stoned. So Tess Hutchinson has already been noticed by people as one who is not entirely part of the group. Before the drawing she is friendly with the other women, pretending to be pleased to be present. The very moment that she sees is her family that draws the black dot, though, her egotism is evident. “You didn’t give him time enough to take any paper he wanted. I saw you. It wasn’t fair!” (Jackson 504). She continues to scream about the unfairness of the ritual up until her stoning. Mrs. Hutchinson knew the lottery was wrong, but she never did anything about it. She pretends as much as she could to enjoy it, when she truly hated it all along. Maybe Jackson is suggesting that the more hypocritical one is, the more of a target they are. Mrs. Hutchinson was clearly the target of her fears. I think sometimes we have no problem remarking on people’s adultery until it is ourselves that...

#### Mr Ahmed

...May I beg that you will write at once to the mother of this unfortunate woman--to Mrs. Catherick--to ask for her testimony in support of the explanation which I have just offered to you?" I saw Miss Halcombe change colour, and look a little uneasy. Sir Percival's suggestion, politely as it was expressed, appeared to her, as it appeared to me, to point very delicately at the hesitation which her manner had betrayed a moment or two since. I hope, Sir Percival, you don't do me the injustice to suppose that I distrust you," she said quickly. "Certainly not, Miss Halcombe. I make my proposal purely as an act of attention to YOU. Will you excuse my obstinacy if I still venture to press it?" He walked to the writing-table as he spoke, drew a chair to it, and opened the paper case. "Let me beg you to write the note," he said, "as a favour to ME. It need not occupy you more than a few minutes. You have only to ask Mrs. Catherick two questions. First, if her daughter was placed in the Asylum with her knowledge and approval. Secondly, if the share I took in the matter was such as to merit the expression of her gratitude towards myself? Mr. Gilmore's mind is at ease on this unpleasant subject, and your mind is at ease—pray set my mind at ease also by writing the note." "You oblige me to grant your request, Sir Percival, when I would much rather refuse it." With those words Miss Halcombe rose from her place and went to the writing-table. Sir Percival thanked her, handed her a...

#### The Virgin

...He went to where Miss Mijares sat, a tall, big man, walking with an economy of movement, graceful and light, a man who knew his body and used it well. He sat in the low chair worn decrepit by countless other interviewers and laid all ten fingerprints carefully on the edge of her desk. She pushed a sheet towards him, rolling a pencil along with it. While he read the question and wrote down his answers, she glanced at her watch and saw that it was ten. "I shall be coming back quickly," she said, speaking distinctly in the dialect (you were never sure about these people on their first visit, if they could speak English, or even write at all, the poor were always proud and to use the dialect with them was an act of charity), "you will wait for me." As she walked to the cafeteria, Miss Mijares thought how she could easily have said, Please wait for me, or will you wait for me? But years of working for the placement section had dulled the edges of her instinct for courtesy. She spoke now peremtorily, with an abruptness she knew annoyed the people about her. When she talked with the jobless across her desk, asking them the damning questions that completed their humiliation, watching pale tongues run over dry lips, dirt crusted handkerchiefs flutter in trembling hands, she was filled with an impatience she could not understand. Sign here, she had said thousands of times, pushing the familiar form across, her finger held to a line, feeling the impatience grow at sight of the man...

#### Missed Appt

...Article 86 of the Uniform Code Of Military Justice. This Article covers Point and Place of Duty. That means from PT formation to COB that is where you will be. What a lot of Soldiers do not understand that includes appointments made by them or someone else. We have appointment times, SP times, formation times and many other start times that dictate we will be there. If a Convoy has an SP time of fifteen hundred hours and the Soldiers decide to show up late because they did not feel like getting ready on time people could die. If they rolled out on time, they may have avoided the ambush or avoided the Vbid that hit them in the bottleneck. It sounds extreme but time management plays a critical role in the Army. When you make an appointment that spot has been reserved for you. That means if you have been given the last slot someone else is going to have to wait for another one to open up. This could be one day or one month. And because you missed it someone else is still going to have to wait when they could have had that spot and been there. If you are going to miss the appointment or cannot make it due to mission they do allow us to cancel the appointment with in twenty four hours. The Army allows us to make appointments for whatever we need. Be it for a medical appointment, house goods, CIF, Smoking Sensation or whatever we need these recourses are available to us. But when Soldiers start missing appointments theses systems start to become inefficient. What a lot of Soldiers do...

#### Angelina Jolie

...When most people see the name Angelina Jolie they only think of the talented actress, the significant other of Brad Pitt or the celebrity with the very diverse children but she is so much more than that. Since 2001 Jolie has been working alongside the United Nations High Commissioner for Refugees to bring awareness to the unfortunate situations of refugees from around the world. She has traveled to and volunteered in many third world countries such as; Sierra Leone, Cambodia, Costa Rica, Iraq and North Caucasus.

#### A Gabe of Sky

...A Gap of Sky A) In the short story “A Gap of Sky” we follow a young woman on her quest for the essence of life. Throughout the story, which stretches across an afternoon, she digs deeper into herself, through sleepiness, drugs, university and a general indifference towards life, until she sees herself, on a grey afternoon in the centre of London, “filled with something fizzing and alive and beautiful”. Ellie wakes up around 4 pm after a rough night with alcohol and various drugs that ended on a rooftop somewhere in London. She remembers that she felt happy that early morning, affected by the drugs and the surreal surroundings, but as she wakes up in her wretched little apartment, the joy of last night seems far away. She needs to hand in an essay on Virginia Wolf the next morning, so she rushes of to get some printer ink, cigarettes and possibly also some more coke. Ellie seems tired, worn out from last night and you understand that she has a hard time getting out of bed. You might get the impression that her life is a bit shallow, for instance when she tells that last night she was surrounded by people who laughed and had a good time, but now she is alone, coping with the harsh realities of a Monday morning. She seems tough, or wanting to seem tough, but she changes towards the end of the short story to a more real toughness of calm confidence. The core of Ellie's life isn't exactly to fulfil society's or her parent's wishes for a bright young woman. She has already had...

...and bodybuilding, going on to compete in several minor contests in Europe. However, it was when he emigrated to the United States in 1968 at the tender age of 21 that his star began to rise. Up until the early 1970's, bodybuilding had been viewed as a rather oddball sport, or even a mis-understood "freak show" by the general public, however two entrepreneurial Canadian brothers Ben Weider and Joe Weider set about broadening the appeal of "pumping iron" and getting the sport respect, and what better poster boy could they have to lead the charge, then the incredible "Austrian Oak", Arnold Schwarzenegger. Over roughly the next decade, beginning in 1970, Schwarzenegger dominated the sport of competitive bodybuilding winning five Mr. Universe titles and seven Mr. Olympia titles and, with it, he made himself a major sports icon, he generated a new international audience for bodybuilding, gym memberships worldwide swelled by the tens of thousands and the Weider sports business empire flourished beyond belief and reached out to all corners of the globe. However, Schwarzenegger's horizons were bigger than just the landscape of bodybuilding and he debuted on screen as "Arnold Strong" in the low budget Hercules in New York (1969),...
