Abstract
A tunable delay circuit includes a first multiplexer, a delay chain, and a second multiplexer. The first multiplexer selects an input signal or a feedback signal as a first output signal according to an enable signal. The delay chain delays the first output signal for different time periods so as to generate a plurality of delay signals. One of the delay signals is used as the feedback signal. The second multiplexer selects one of the delay signals as a second output signal according to a pass signal.
