looking for performance of amp first, find qpoint via DC analysis second, compute open circuit time constants apply miller's theorem do hand computation, it gets hairy here find Vo/Vin one way to work through is to iteratively plug in values of Vs from midband, band edges, and out of band put it in bode plotter (bodey) KCL ftw solve them get Vo/Vs ends up being a 3x3 matrix to solve voltage amplifier, series/shunt, end up with Af = A/(1+AB) Rin_feedback = Ri(1+AB) Ro_feedback = Vo/Io = Ro/(1+AB) shunt/shunt, transresistance amp, Af = Vo/Is = A/(1+AB) Rin_feedback = Vi/Ii = Ri/(1+AB) Ro_feedback = Vo/Io = Ro/(1+AB) series/series, transconductance amp, Af still the same Rin_feedback = Ri(1+AB) Ro_feedback = Vo/Io = Ro(1+AB) shunt/series, current amp Rin_feedback = Ri/(1+AB) Ro_feedback = Vo/Io = Ro(1+AB)
