Abstract

PURPOSE:To use only one operational amplifier, independently of the number of stages of delay, by making time division for the signal transfer. CONSTITUTION:A signal is inputted from an IN terminal and outputted from taps 1-6 with 1T-6T (where; T is a unit delay time) of delay. Each switch SW0-5 is conductive when clock pulses are at high level and interrupted when at low level. Thus, taking the clock pulse 0 as a reference, clock pulses are at high level in the order of 0, 1, 2...5 at one period T, and the switches SW0, SW1...SW5 are correspondingly conductive. That is, the charge of capacitors C2-C6 is shifted right in time division during the period T and a new input signal is fetched to a capacitor C1. When the operation of one period is finished, an analog input signal different from the time by one period T respectively to the capacitors C1-C6. This signal is picked up via a buffer from the taps 1-6 at each delay.
