ABSTRACT:
A noise reduction circuit having an amplification arrangement including first and second voltage-follower amplifiers coupled to a low-pass filter for providing symmetrical push-pull operation on an input signal so that an output voltage offset of an output signal is suppressed. The amplification arrangement provides symmetrical operation substantially independent of temperature.
