Question:

An ac schematic of a local shunt-shunt feedback circuit is shown in Fig. 8.57. Take R_F= 100 kÎ© and R_L= 15 kÎ©. For the MOS transistor, I_D= 0.5 mA, W/L = 100, k€™ = 180 µA/V², and r_o= ˆž. Calculate input resistance, output resistance, loop transmission, and closed-loop gain:

(a) Using the formulas from two-port analysis (Section 8.5).

(b) Using the formulas from return-ratio analysis (Section 8.8).
