Consider a CS amplifier having gm = 2 mA/V, ro = 20 k, RL = 20 k, Rsig = 20 k, Cgs = 20
Chapter 10, Problem 10.29(choose chapter or problem)
Consider a CS amplifier having gm = 2 mA/V, ro = 20 k, RL = 20 k, Rsig = 20 k, Cgs = 20 fF, Cgd = 5 fF, and CL = 5 fF. (a) Find the voltage gain AM and the 3-dB frequency fH (using the method of open-circuit time constants) and hence the gainbandwidth product. (b) Repeat (a) for the case in which a resistance Rs is connected in series with the source terminal with a value selected so that gm Rs = 2 .
