Abstract
A delay circuit respectively delays rising and falling edges of an input signal. The delay circuit comprises first and second delay lines, a control circuit, and first and second logic circuits. The first delay line delays the first input signal the first delay time to output the first delay output signal. The second delay line delays the first input signal the second delay time to output the second delay output signal. The control circuit outputs the control signal according to the first input signal. The first logic circuit receives the first delay output signal and outputs the first output signal according to the control signal and the first input signal. The second logic circuit receives the second delay output signal and outputs the second output signal according to the control signal and the first input signal. The first and second delay times are different.
