Abstract:
1. A pulse generator, comprising: a control circuit, receiving a reference clock signal and a data signal, and for generating a clock enable signal and a delay selecting signal according to the reference clock signal, wherein the control circuit generates the clock enable signal when a state of the data signal changes; a clock gating unit, coupled to the control circuit, for receiving the reference clock signal and the clock enable signal, and for passing the reference clock signal according to the clock enable signal, to generate a clock gated signal; a delay module, coupled to the clock gating unit, for delaying the clock gated signal according to the delay selecting signal to generate a target clock signal; and a pulse signal generating unit, coupled to the delay module, for generating a pulse signal according to the target clock signal, wherein a width of the pulse signal is determined by the delay selecting signal.
