A signal generating circuit includes a first circuit, a tracking circuit, and a delay circuit. The delay circuit is coupled with the first circuit and the tracking circuit. The first circuit is configured to receive a first clock signal and an output signal from an output of the delay circuit, and to generate a second clock signal and at least one first tracking signal. The tracking circuit is configured to receive the at least one first tracking signal and to generate a second tracking signal. The delay circuit is configured to receive the second clock signal and the second tracking signal and to generate the output signal.
