What is a lowest and highest values of a0


Solve the below:

Q: A NMO Stransistor is fabricated in the 0.18-μmprocess whose parameters are given. The device has a channel length twice the minimum and is operated at VOV = 0.25 V and ID = 10 μA.

(a) What values of gm, ro, and A0 are obtained?

(b) If ID is increased to 100 μA, what do VOV , gm, ro, and A0 become?

(c) If the device is redesigned with a new value of W so that it operates at VOV = 0.25 V for ID = 100 μA, what do gm, ro, and A0 become?

(d) If the redesigned device in (c) is operated at 10 μA, find VOV , gm, ro, and A0.

(e) Which designs and operating conditions produce the lowest and highest values of A0? What are these values? In each of these two cases, ifW/L is held at the same value but L is made 10 times larger, what gains result?
