Abstract

PURPOSE:To obtain amplifiers with high input impedance and low output impedance by connecting a resistor between the output of a high-gain out-of-phase amplifier connected to the output of a differential amplifier and one input of the differential amplifier. CONSTITUTION:The inversion input of differential amplifier 1 is led to the input of a unit and to its output, high-gain inverting amplifier 2 is connected. This output is connected to the noninversion input of differential amplifier 1 by way of resistor 3 and between this non-inuersion input and ground, a capacitor is connected so as to lead both terminal of this capacitor to output terminals.
