Abstract
A differential operation circuit that uses the differential input signals to generate a reference voltage that fluctuates with the common mode voltage of the differential input signals. The reference voltage includes a common mode component that generally follows the common mode voltage of the differential input signals. The common mode component of the reference voltage is used to fully or almost fully offset the common mode voltage of the differential input signals, thereby increasing the differential operation circuit's common mode rejection characteristics.
