The ac schematics of a common-source stage and a common-sourcecommon-gate (cascode) stage are shown in Fig. 7.43

Question:

The ac schematics of a common-source stage and a common-source€“common-gate (cascode) stage are shown in Fig. 7.43 with R_S= 10 kÎ© and R_L= 20 kÎ©. Using the transistor and operating-point data in Problem 7.2:

(a) Calculate the low-frequency, small-signal voltage gain Ï…_o/Ï…_i for each circuit.

(b) Use the zero-value time-constant method to calculate and compare the ˆ’3-dB frequencies of the gain of the two circuits.
