Abstract
An input signal is supplied to the non-inverting input terminal of a current differential amplifier. A capacitor is connected between the output terminal of the current differential amplifier and a power source and the capacitor stores charges according to an output signal of the current differential amplifier. The input signal and an output signal of the current differential amplifier are supplied to resistors via buffer circuits and signals divided by the resistors are added together by a buffer circuit and output from an output terminal and at the same time fed back to the inverting input terminal of the current differential amplifier.
