Question

4. The MOSFET in the circuit given below has Vi- 1 V, kn 0.8 mA/V2, and VA 40 V a) Find the values of Rs, Ro, and Ro so that Io -0.1 mA, the largest possible value for RD is used while a maximum signal swing at the drain of tl V is possible, and the input resistance at the gate is 10 MS2. b) Find the values of gm and ro at the bias point c) If terminal Z is grounded, terminal X is connected to a signal source having a resistance of 1 M12, and terminal Y is connected to a load resistance of40 k12, find the voltage gain from signal source to load is the output resistance of the source follower? signal current of 10 μΑ and having a resistance of 100 kQ, find the voltage signal that d) If terminal Y is grounded, find the voltage gain from X to Z with Z open-circuited. What e) If terminal X is grounded and terminal Z is connected to a current source delivering a can be measured at Y. For simplicity, neglect the effect of ro. +5 V RD トz -5 V
