The attachment is equivalent circuit of an amplifier.
I know that the gain of the circuit is \(-g_{m}R_{L}\). In next exercise require to compute gain if \(r_{\pi }\) (resistor in the input) approach to infinity. Then, I see no difference in gain of the circuit.
It make me curious, if the gain isn't depend on \(r_{\pi }\) then I can choose any value?
