ECE 3050 – Spring 2004 Page 1 Homework Assignment No. 12 Due on Monday, April 5, 2004 1.) Problem 18.23 (18.16) of the text. 2.) A shunt-shunt feedback amplifier is shown. Use the methods of feedback analysis to find the numerical values of v2/v1, v1/i1, and v2/i2. For Q1, assume that hfe = 100, gm = 50mS and ro = ∞. For M2, assume that gm = 1mS and rds = ∞. 3.) For each of the MOSFET amplifiers shown below, show how to connect a single resistor from the output to the input that achieves a series-shunt, series-series, shunt-shunt and shunt-series negative feedback amplifier. For each of the four configurations, identify on the schematic the correct variables (voltage or current) for xs, xf, xi, and xo. The outputs should be at the drain or source of M3.
