Abstract
PURPOSE: To exactly execute a stable amplification, by discriminating rise and fall of an input signal, sample-holding a DC component by this discrimination output, and differentially amplifying this sample-holding output and the input signal.
CONSTITUTION: An input signal Si is applied to an averaging circuit 3 through a low-pass filter 1 and a phase inverting circuit 2, and is averaged. Also, the input signal is applied to a discriminating circuit 4 and rise and fall of the input signal are discriminated. A transistor GT of a holding circuit 5 is turned off by a rise discrimination output signal of this discriminating circuit 4, the transistor GT is turned on by a fall discrimination output signal, and a signal of the holding circuit 5 is made to follow an output signal of the averaging circuit 3. In this way, the output signal and the input signal of the holding circuit 5 are applied to a differential amplifying circuit 6 so that they are differentially amplified.
