Chapter 10, Problem 10.76(choose chapter or problem)
Consider a bipolar cascode amplifier biased at a current of 1 mA. The transistors used have = 100, ro = 100 k, C = 10 pF, C = 2 pF, Ccs = 0, and rx = 50 . The amplifier is fed with a signal source having Rsig = 5 k. The load resistance RL = 2 k. Find the low-frequency gain AM , and estimate the value of the 3-dB frequency fH .
