Abstract

PURPOSE:To obtain characteristics by the first impedance components and the second impedance components, by constituting the second impedance components, which controls a signal voltage level applied to the noninversion input terminal, by resistances and capacitors. CONSTITUTION:An input signal source 2 and the first impedance components 3 are connected in series between the noninversion input terminal (+) and the inversion input terminal (-) of a differential amplifier 1, and one end of the second impedance components 4 which controls a signal voltage level applied to the noninversion input terminal (+) is connected between the input signal source 2 and the noninversion input terminal (+), and the other end of the second impedance components 4 is grounded, and a negative feedback circuit 5 is inserted between the output terminal and the inversion input terminal (-) of the differential amplifier 1 to superpose a negative feedback voltage to the signal source 2, and the input signal voltage with the negative feedback voltage and the signal source voltage superposed is equalized in respect to phase by the first and the second impedance components. The second impedance components consist of resistances 41 and 42 and capacitors 43 and 44.
