PROBLEM TO BE SOLVED: To reduce a load variation of a power circuit 1 on each cycle basis.SOLUTION: A variable delay circuit includes: a delay stage in which delay units are connected in cascade; a compensation stage, having the same configuration as the delay stage, to which a signal delayed in the delay stage is input; a power circuit 1 which supplies power to each delay unit in the delay stage and the compensation stage; and a control circuit 21 which controls each switch in the delay stage and the compensation stage. The control circuit 21 controls each switch to make constant the total sum of load capacity which is set to be a connection state at the output terminal of a non-inverted buffer in the delay stage and the compensation stage. |
