Skip to Main Content. A not-for-profit organization, IEEE is the world's largest technical professional organization dedicated to advancing technology for the benefit of humanity. Use of this web site signifies your agreement to the terms and conditions. A three opamp instrumentation amplifier have been designed by using two simple op-amps at the two input stages and a folded cascode opamp at the output stage. Both op-amps at the input and output are 2-stage.
The commonly used Instrumentation Amplifier using Op Amp is one using three op amps. This circuit provides high input resistance for accurate measurement of signals from transducers. In this circuit, a noninverting amplifier is added to each of the basic difference amplifier inputs. The circuit is shown in the Fig.
