Problem 1: (4 pts) The circuit below uses current source biasing and two amplifier stages. Assume the transistors are biased so they have the same 9m and ro values, and that the current sources have output resistance ro equal to the ro of the two transistors. In other words, in the small signal model you will replace the de current sources with resistors of value ro Q2 Ui Q1 U) (a) Draw a small-signal model for this amplifier. Be sure...

Draw the circuit of a common source amplifier, which is biased by a MOSFET current mirror, and which uses only one capacitor and two resistors (including the RREF of the current mirror). Assume that the input to the amplifier is a zero-DC signal. Then, design the amplifier to achieve a gain Avo--gRo =-4V/V, and an output resistance Ro-Ro-1K. Ignore channel modulation. Assume that all MOSFETS are identical with VIN-1V, and Kn = 2mA/V. Use Vo = 5V and Vs =-5V....
