Abstract
A delay circuit is disclosed. A switched-capacitor group includes a plurality of switched-capacitor units, each of which have a switching element and a capacitive element charged/discharged by turning on/off the switching element. The switched-capacitor units are connected such that the input signal is input in common to all of the switched-capacitor units and the capacitive elements are charged as well such that the capacitive elements are discharged to allow the output signal to be output from the switched-capacitor units. A switching control unit performs on/off control of the switching elements to cause the capacitive elements to be charged in sequence based on the input signal, causing the capacitive element charged last time to be discharged to allow the output signal to be output in sequence from the switched-capacitor units, and performs control of all of the switching elements to be turned off upon on/off switching of the switching elements.
