APPLICATION NOTE 1960
Simple Pulse Generator Has Low Parts Count

With a few op amps and some external components, you can build a pulse generator with variable frequency
and duty cycle.


The natural choice for generating a pulse of variable frequency and duty cycle is a good bench-top pulse
generator. If you don't have a generator or must build one into your system, however, you can do it with a few
op amps and some external components (Figure 1).




Figure 1. This simple and versatile pulse generator includes only 15 components.
