This simple circuit generates narrow pulses at about 700-800Hz frequency. The pulses, containing harmonics up to the MHz region, can be injected into audio or radio-frequency stages of amplifiers, ...

In IC design, the typical approach for generating a pulse width-modulated (PWM) signal from an analog value (such as in the control loop for a switch mode power supply) uses a ramp or triangle wave ...

I have wanted to make a pulse generator for years. I know you can buy perfectly good ones, but not if you want non-overlapping outputs to drive the mosfets in synchronous-rectified dc-dc converters.
