Suppose you have a transconductance amplifer with infinite input impedance and transconductance Gm. There is a feedback resistor from output back to input (Rf). There is a load resistor from the output to Ground (RL) . Find the input impedance as a function of Gm, Rf, Rg.
1 Answers↳
start out with special cases. if Gm* RL = 1, then Vout = Vin and Zin = infinite. If Gm = 0, then Rin = RL+ Rout To get general solution, use KCL and KVL Less
