Abstract

PURPOSE:To avoid the waveform distortion or the like which is caused by the frequency characteristics of the capacity component, by securing an equal input signal voltage between the two input terminals in terms of phase with two impedance components connected to the input terminals of a differential amplifier or by other methods. CONSTITUTION:An input signal source 2, the 1st and 2nd impedance components 3 and 4 plus negative feedback circuits 5 and 6 are connected to the input and output terminals of a differential amplifier 1 as shown in the diagram. Then the input signal voltage in which the negative feedback voltage is superposed on the signal source voltage is made equal between a nonreverse input terminal and a reverse input terminal in terms of phase by the components 3 and 4. For instance, the output voltage and the internal impedance of the source 2 are referred to as Vi and Zi respectively, the impedances of the components 3 and 4 are Z1' and Z2, and the internal resistance of the negative feedback circuit is Rbeta. Thus the following relation is satisfied: Vi=k1.(Zi+Z1')/(Z2+Rbeta), where k1 is the proportion constant.
