CMRR in Voltage-Op-Amp-Based Current-Mode Instrumentation Amplifiers (CMIA)

Abstract

The common-mode rejection ratio (CMRR) of a power-supply current-sensing current-mode instrumentation amplifier (CMIA) has theoretically been analyzed and formulated. The theory was further investigated by doing experiments using mu A741 and TL071 as op-amps and CA3096 transistors as the current mirrors of the CMIA. Both theoretical and practical… (More)
