(a) Calculate RE to make the BJT's operating point (Q-point) current ICQ = 2 mA. (b) Assuming ro = ∞ and CE = ∞, draw the small-signal equivalent circuit of the amplifier and calculate the amplifier's input resistance (Rin), output resistance (Rout), and voltage gain (Av). (c) Assuming ro = ∞ and CE = 0, draw the small-signal equivalent circuit of the amplifier and derive the expression for the voltage gain (Av). Then, calculate the value of Av. (d) Assuming ro = 10 kΩ and CE = 0, draw the small-signal equivalent circuit of the amplifier and derive the expressions for Rin , Rout , and Av. Then, calculate their values.

1. (18 points total) In the circuit shown below, the PMOS transistor has Vtp = −0.8 V, VA = −28 V, and operates with VD = 3 V. Note the 22 MΩ gate resistor, which is another way to bias a CS stage, used here in addition to the current source. You may assume that any channel length modulation does not appreciably affect the DC biasing. (a) Draw the small-signal equivalent circuit for this transistor amplifier. Be sure to label the input and output voltages as well as the source, gate and drain locations on the schematic. Calculate all parameters/component values used in your equivalent circuit that were not given in the problem. (6 points) (b) What is the input resistance of the amplifier? What is the output resistance? (6 points) (c) What is the voltage gain Av = vo/vi? How much does your calculation change if you assume RG → ∞? (6 points)
