The voltage gain of an amplifier is described in the s-domain as shown below. Av(s) = -gm R1/R1 + 1/sC1 (R2 || sC2) a) Determine the pole(s) if any. Show your work! b) Determine the zeros(s) if any. Show your work! c) Crudely graph a straight line approximation for the Bode Plot of the voltage gain as function of frequency. Label key values and slopes. You may make reasonable approximations for the relative values of poles and zeros. In other words, you may assume that a particular pole/zero is larger than another, and that choice is yours.
