A CS amplifier that can be represented by the equivalent circuit of Fig. 10.16 has Cgs-2 pF, Cgd = 0.1 pF, CL = 2 pF, gm = 4 mA/V, and Rsig = R'L = 20 k Ω . Find the midband gain AM, the input capacitance Cin using the Miller Effect, and hence an estimate of the 3-dB frequency fH. Also, obtain another estimate of fμ using open-circuit time constants. Which of the two estimates is more appropriate and why?
