In the circuit of Fig. P3.57 let the FET have Vt 5 1.5 V, k 5 0.5 mA/V2 , and 5 0.01 V21 . (a) Find the dc operating point of the FET, assuming 5 0 to simplify your dc calculations. (b) Find the gain voyvi . (c) Use the test method to fi nd Ri (the input resistance with the output port open-circuited), and use inspection to fi nd Ro (the output resistance with the input port short-circuited).
