25 ELECTRICAL ENGINEERING DEPARTMENT California Polytechnic State University EE 361 Operational Amplifier (Op-Amp) Circuits Part 1 Pre-lab 4 Voltage Follower, Non-Inverting Amplifier & Inverting Amplifier 1. Prove the closed-loop gain (V o / V i ) for the op-amp circuit below equals 1. +12V -12V + - V+ V- V O V 1 2. Derive the closed-loop gain (V o / V 1 ) for the op-amp circuit below. Also, can this op-amp circuit “attenuate” a signal? Why or why not?
