Inverting amplifier circuit (Rev. B)

 

This designinvertsthe inputsignal,Vi, and appliesa signalgain of –2 V/V. The inputsignaltypicallycomesfroma low-impedancesourcebecausethe inputimpedanceof this circuitis determinedby theinputresistor,R1. The common-modevoltageof an invertingamplifieris equalto the voltageconnectedtothe non-invertingnode,whichis groundin this design.
