Abstract

PURPOSE:To compensate the influence of field through and the deterioration of a gain frequency characteristic at signal input by connecting a low-pass type amplifier circuit at the post-stage of an output stage buffer circuit and integrating the said circuit by uniting it with a sample holding circuit. CONSTITUTION:The output terminal voltage of an output stage buffer circuit 7 is obtained by superposing a high freqeucny analog input signal to DC voltage and varies in the same frequency as that of the input signal. Since the gain frequency characteristic of an input stage buffer circuit 4 is deteriorated at the input of a high frequency signal, the voltage value held by a holding capacitor 6 is less than that of the input signal. If a holding signal obtained by superposing the high frequency analog input signal to the DC signal and attenuated in comparison with the input signal is applied to a low-pass type amplifier circuit 8, the high frequency input signal leadked into the holding capacitor 6 can be removed by the low frequency passing function of the low-pass type amplifier circuit 8.
