Add-On Pulse Generator Circuit

Posted on Apr 28, 2012

This pulse generator can supplement a standalone pulse generator. Using a transistor and a 555 timer, pulse widths of 5 to 500 can be produced. The value of C3 is approximately found from the formula: C3 uF = 1.1 x10-5 T where T is the shortest pulse width (uS) desired in a 10:1 range (T should be greater than 5uS).
