发明名称 Common mode rejection calibration method for difference amplifiers
摘要 A common mode rejection calibration scheme for use with a difference amplifier having an associated signal path. A signal is generated which varies with the common mode voltage of the differential input voltage applied to the amplifier. This signal is scaled and coupled into the signal path such that the scaled signal reduces the common-mode error that would otherwise be present in the difference amplifier's output.
