8. Given this two-port representation of an op amp with stage 1 being the diff pair, stage 2 being the middle gain, and stage 3 being the output circuit, calculate the overall voltage gain from Vsig to load RL. Ro1 I Av1'Vin1 Ro2 Av2*Vin2 Rsig RI2 RI3 Ro3 Av3*Vin3 |RL Vsig Rsig=120 Ohms, Ri1=2k, Av1=30, Ro1=1k, Ri2= 5k, Av2=200, Ro2=1k, Ri3=200k, Av3=0.9, Ro3=140 Ohms and RL = 100 Ohms

An operational amplifier also called op amp is an integrated circuit or analog circuit that takes input as a differential voltage and produces output as a single-ended voltage. It is an IC that can amplify weak electric signals.An op amp has one output p…
