ABSTRACT:
A differential input receiver having normal and common mode impedance balanced inputs and a common mode rejection ratio approaching infinity is provided. The receiver includes a differential input operational amplifier across which is connected a fixed gain inverting amplifier. The fixed gain, inverting amplifier being connected in a feedback configuration across the differential input amplifier. Additionally, the values and ratios of the various resistors being selected to provide the balanced differential input and the substantially zero common mode gain of the receiver.
