Mastering presents homework items assigned by your instructor and works with you to answer them. Homework items typically have an introduction, possibly figures, and one or more parts for you to answer. Part A What is the magic number in (Figure 1)? You could try to guess the magic number but you would probably use up all your tries before getting the correct answer. Notice the View Available Hint(s) link underneath the question statement for this part. Selecting this link will open up a list of hints that will guide you to the correct number. Hint 1 for Part A. How to approach the problem Notice that there are two hints for this question. You are not required to use all of the hints or to use them in order. Each hint has a tagline that describes its contents. Based on the tagline you can decide whether or not a particular hint will be useful to you. Your instructor may choose to give you a bonus for not using hints or to deduct a small penalty for using hints. If you are stuck, using the hints will usually result in a higher score than simply trying to guess because you may lose fewer points for opening a hint than for getting the answer to the main question incorrect. To help you, the magic number is equal to 10⋅x, where x is a number between 1 and 8. Now, open up the second hint to uncover the value of x. Hint 2for Part A. What is x? You are told from the previous hint that the magic number is equal to 10⋅x. For this problem, x is equal to 6. Use this to compute the magic number and enter it below. magic number Part B Multiple-choice questions have a special grading rule determined by your instructor. Assume that your instructor has decided to grade these questions in the following way: If you submit an incorrect answer to a multiple-choice question with n options, you will lose 1/(n-1) of the credit for that question. Just like the similar multiple-choice penalty on most standardized tests, this rule is necessary to prevent random guessing. If a multiple-choice question has five answer choices and you submit one wrong answer before getting the question correct, how much credit will you lose for that part of the question? 100% 50% 33% 25% 20%

At the end of this assignment is a set of characteristic curves for an n-channel JFET. Print out the curves, and look at the one labeled "nJFET #1." The curves are label with the gate-source voltage (VGS) values. (a) Estimate the IDSS from the curve. (b) Estimate the gate-source threshold voltage VT. (c) Plot the load line on the graph when the nJFET is used in this circuit. (d) We want to set the quiescent point to be near the middle of the full possible output voltage range (about halfway between 0V and VDD = 15V). Mark the quiescent point with "Q" on the load line. (e) What is the transconductance near the quiescent point? (f) What should the DC voltage be set to in order to properly bias the transistor? (Assume that the DC voltage can be adjusted to any positive or negative value, and that the AC amplitude is zero for now). (g) The AC voltage now has an amplitude of 0. 5V (in other words, VG oscillates ±0. 5V around the VDC value). Use the graph to determine the maximum and minimum values for the drain current. (h) Based on the max and min drain currents, what are the max and min values for Vout ? And based on this peak-peak output swing, what is the AC gain of the circuit? (i) What is the AC gain of the circuit of you calculate it directly from the transconductance and the circuit components?

a) Assuming we can control the VIN between 0.5 V and 2.5 V, find the maximum value for resistor R as a function of VIN for the NMOS to stay in saturation. Note: The pullup resistor R is preferred to be large, a bit too large, and we go into the linear region of operation. b) Assume we want to keep the VOUT at 1.5 V, and ID at 200 uA. What should be the values for bias voltage VIN and resistor R? c) Based on part (b) values, find the maximum and minimum values for VOUT and VIN so that the NMOS stays in saturation. d) Based on part (b) values, find open circuit small signal gain, AV. Hint: Need to find values for gm and g0 first. For the following NMOS amplifier (driving load RL ) with the following parameters: Vdd = 2.5v Vbs = 0 RL = 10 k Vt0 = 0.5v lambda = 0.11v-1 W/L = 10 unCox = 200.0 uA/V2 Suppose the load resistor, RL, is not connected (open circuit):
