The invention provides a switching circuit and a clock pulse supply circuit, and the switching circuit is coupled with a first oscillation circuit and a second oscillation circuit. The first oscillation circuit generates a first clock pulse signal according to a first enable signal. The second oscillation circuit generates a second clock pulse signal according to a second enable signal. The switching circuit takes the first clock signal or the second clock signal as an output clock according to a selection signal. The switching circuit comprises a first D-type flip-flop and a second D-type flip-flop. The reset end of the first D-type flip-flop receives the first enable signal. The reset end of the second D-type flip-flop receives the second enable signal. 本发明提供了一种切换电路以及时脉供给电路，该切换电路，耦接一第一振荡电路以及一第二振荡电路。第一振荡电路根据一第一使能信号，产生一第一时脉信号。第二振荡电路根据一第二使能信号，产生一第二时脉信号。切换电路根据一选择信号，将第一或第二时脉信号作为一输出时脉。切换电路包括一第一D型触发器以及一第二D型触发器。第一D型触发器的重置端接收该第一使能信号。第二D型触发器的重置端接收该第二使能信号。
