Abstract
A chopper circuit has a delay circuit that delays a received control signal and a difference detection circuit that detects a difference between a control signal delayed by the delay circuit and the received control signal. A first threshold based on which the delay circuit checks a change in the received control signal and a second threshold based on which the difference detection circuit checks a change in the received control signal are realized with a common threshold.
