Abstract
A signal generation circuit includes a first delay circuit, a second delay circuit, and a duty control circuit. The first delay circuit delays a first input signal to generate a first output signal. The second delay circuit delays a second input signal to generate a second output signal. The duty control circuit compares phases of the first and second output signals and changes the value of the second delay control signal, and then decreases the times, by which the first and second input signals are delayed, by the same value.
