Abstract

PURPOSE:To take out exclusively a required pulse signal of a good S/N with a simple constitution, by making an amplifying circuit, to which an input signal is supplied, constituted of differential amplifiers which are connected to perform the negative feedback non-inversion amplification operation. CONSTITUTION:An input signal A from a terminal 1 is supplied to the + side terminal of a differential amplifier 10, and an output signal B of the amplifier 10 is inputted to - side terminals of amplifiers 10 and 20 through the + side terminal of the pulse shaping differential amplifier 20 of the next stage and a peak hold circuit consisting of a diode D1 and a time constant circuit (consisting of resistances R3 and R4 and a capacitor C2). The signal B is supplied to the C2, and a terminal voltage V3 of the C2 is clamped to be equal to a peak level VP of the output from the amplifier 10, and the amplifier 10 performs the negative feedback non-inversion amplification operation to amplify only the part near the peak level of the signal A. Since the amplifier 20 compares the signal B with a voltage V2 approximately equal to the voltage V3 and amplifies it only a required pulse of a good S/N is shaped and outputted.
