Abstract

PURPOSE:To ensure the steady operation property through a simple constitution by converting the same signal as the input signal applied to the inverse amplifier circuit into the fixed property through the nonlinear circuit and then applying the converted input signal to the noninverse input terminal of the operational amplifier within the noninverse amplifier circuit. CONSTITUTION:When input signal EI is applied between input terminal P1 and input/output common terminal P2, circuit 2 does not operate in case the relation of ¦EI¦<=¦VZ¦ is obtained between the absolute value of signal EI and Zener voltage VZ of constant voltage diode ZD of nonlinear circuit 2. Thus, offset voltage VOF applied to noninverse input terminal S2 of operational amplifier A in inverse amplifier circuit 1 also becomes zero. So circuit 1 functions as a mere inverse amplifier. Accordingly, circuit 1 functons as a differential amplifier circuit in which voltage VOF proportional to signal E1 is applied to terminal S2 of circuit A. As a result, the operation property which is steady and identical to the conventional operation can be obtained.
