CHAPTER 4: SIGNAL TO NOISE RATIO - Pace University

Instrumentation amplifiers are composed of three op amps. Op amp A and op amp B make up the input stage of the instrumentation amplifier in which the two op amps are cross coupled through three resistors. The second stage of the module is the difference amplifier of op amp C. The overall gain of the circuit is given by: (o = K(2a + 1)( (2 - (1) ................
