Find the voltage gain of the overall circuit, Electrical Engineering

Assignment Help:

Q. Find the voltage gain of the overall circuit?

(a) Consider the circuit of the inverting amplifier shown in Figure (a), including an ideal op amp. Show that the voltage gain of the overall circuit vo/vi is independent of the op-amp parameters.

(b) Without considering the op-amp gain to be infinite, investigate the effect of a finite value of A, the open-circuit voltage amplification of the op amp, on the voltage gain of the overall circuit.

(c) Let Ri = 2k and Rf = 80 k in Figure (a). Find the voltage gain of the overall circuit: (i) if the op-amp gain is infinite, and (ii) if the op amp gain is 100.
