Abstract

PURPOSE:To improve the SN ratio of an analog signal amplifier circuit by exercising switching control by a control signal synchronizing with an input signal over a switching circuit, which varies in impedance, provided in parallel to the output load of the amplifier. CONSTITUTION:Analog signal Va is periodically sent out from signal source 1 and led to one input of differential amplifier 2, where it is compared with reference voltage REF supplied to the other input to output a binary signal showing their magnitude relation. The output of differential amplifier 2 is supplied to level converter 3 and also led to switching circuit 4 by being branched, and the output of level converter 3 is led to the output terminal by way of latch circuit 5. Signal source 1, level converter 3, switching circuit 4, and latch circuit 5 are all supplied with synchronizing clock signals.
