8.22 Consider a cascode amplifier for which the CS and CG transistors are identical and are biased to operate at ID = 0.1 mA with VOV = 0.2 V. Also let VA = 2 V. Find Av1, Av2, and Av for two cases: (a) RL = 20 kΩ and (b) RL = 400 kΩ.
(a) –1.82 V/V, 10.5 V/V, –19.0 V/V; (b) –10.2 V/V, 19.6 V/V, –200 V/V
