An NMOS transistor in the amplifier circuit of Fig. 2 has V_(t) = 1V, k_(n) = 4m(A)/(V^(2)). Assume V_(DD) = 10V, R_(G1) = 6MΩ, R_(G2) = 4MΩ, R_(S) = 1kΩ, and R_(D) = 2kΩ. (a) (10 points) Neglect the channel-length modulation and body effect. Find the voltage V_(GS) and the drain current I_(D). Then, find g_(m). (b) (10 points) Find r_(o) if V_(A) = 100V. Then, find the resistance R_(od) looking into the drain terminal of NMOS and the voltage gain (v_(o))/(v_(sig.)). 2.

The likelihood that a patient with a heart attack dies of the attack is 0.04 (i.e., 4 of 100 die of the attack). Suppose we have 5 patients who suffer a heart attack, what is the probability that all will survive? calculate the answer in 2 decimal place. Round off the answer. 0.82 $5! \times (0.96)^5$ $0.04 \times (0.96)^5$ $5 \times (0.96)^5$

Passage 3 3. 'One of the most common problems in old age is mental confusion, a condition extremely detrimental to the quality of life in later years. 2When it's the subject of study, mental confusion in the elderly is divided into three main categories. 3One kind of confusion is purely a result of illness, medication, or emotional and environmental stress. 4This category of confusion is usually reversible if caught early enough. 5The second type of confusion results from damage to the brain due to aging. 6This type is commonly referred to as "dementia." 7The third kind of confusion is produced by severe mental disorders such as psy- chosis.* (Adapted from Waughfield, Mental Health Concepts, p. 283.) Questions What is the topic of the passage? What is the main idea/topic sentence of the passage? Identify the major and minor details of the passage. Make a diagram by using the major and minor details of the passage.

Problem 3. (a) Use Newton's Method with $f(x) = x^3 - 5x^2 - 2x + 8$ and initial value $x = 1$ to find one of the roots of $f(x)$ accurate to 6 decimal places. Write down your approximation at every step, and stop when the first six decimal places are no longer changing from one approximation to the next. (b) Use a graph to estimate good starting values to find the two other roots for $f(x) = x^3 - 5x^2 - 2x + 8$ using Newton's Method, and then use Newton's Method to find the roots accurate to six decimal places, writing down your approximations at each step. Problem 4. Let $f(x) = 2^x + x^2 - e$. (a) Use a graph on your calculator to find a good starting point for Newton's Method for finding the zeroes of $f(x)$. How many zeroes are there? (b) Find all zeroes of $f(x)$ accurate to 6 decimal places, writing down your approximation from Newton's Method at each step.
