<p>A delay circuit acquiring an output signal delayed from an input signal, comprising: a switched capacitor group that includes a plurality of switched capacitor units, wherein each of the plurality of switched capacitor units has a charging MOS transistor and a discharging MOS transistor, and a capacitive element which is connected to sources of the charging and the discharging MOS transistors; and a switching control unit that performs on/off control of the charging and the discharging of the MOS transistors, to cause each of the capacitive elements to be charged in sequence based on the input signal, and that, upon causing the each of the capacitive elements to be charged in sequence based on the input signal, causes the capacitive element charged last time to be discharged, to allow the output signal to be output in sequence.</p> |
