摘要

(assignment) ; It is an object to set a wide range of delays from a signal input to an output while suppressing the circuit scale. ; (Solution) ; A variable delay circuit 100 capable of changing the delay amount from the input of the signal IN to the output thereof, comprising: a first delay portion 101 for delaying the signal IN by a first delay amount and a signal IN; Second delay unit 102 for delaying c) by a second delay amount larger than the first delay amount, and when the delay amount exceeds the maximum delay amount that can be delayed by the first delay unit 101, the delay amount is zero. And a delay amount selector 103 for selecting a signal path that is the sum of the first delay amount and the second delay amount.
