Embodiment Construction
[0049] Below in conjunction with accompanying drawing, the present invention will be further described, ultrafast edge step pulse generation method, and it comprises the following steps:
[0050] A. The clock excitation signal is generated by the high-precision clock reference source 1; the excitation signal of the pulse source comes from the clock reference source 1. The clock reference source 1 can be an external clock or a high-stable crystal oscillator on the pulse source as a clock output. In the selection of the high-stable crystal oscillator clock reference, this embodiment directly introduces a 100KHz clock from the outside, of course, it is also possible to install a 20M clock on the board and obtain a 100KHz clock after frequency division.
[0051]B. After the clock excitation signal enters the pulse source, the excitation signal excites the high-speed comparator 3 to generate a pulse signal with a faster edge; between the high-speed comparator 3 and the clock output...
