Sharp pulse generator circuit

Published:2011/11/27 20:38:00 Author:Ecco | Keyword: Sharp pulse generator

The circuit shown in Figure (a) can produce 2μs sharp pulse. Repetition frequency is determined by the following equation f = 1/2.3C kHz. And C's unit is μF. In the circuit shown in Figure b, adjusting the potentiometer RP can get 1:20 available frequency range . Of course , adjusting the size of the input voltage Ust can change the frequency. Gate device substitution : FLH25J-4700. (View)
