w2aew | #231: Circuit Fun: Stairstep generator using 555 and op amps @w2aew | Uploaded February 2016 | Updated October 2024, 2 hours ago.
Here's an overview and demonstration of an interesting stairstep generator circuit that uses a 555 timer, a pair of op amps and a handful of transistors, diodes and passive components. It is a tutorial of different types of astable pulse generator / oscillator circuits and an interesting pulse integator / accumulator circuit. Thanks to one of my astute viewers (+11zekim), we now know that this integrator circuit is known as a Deboo Integrator.
My friend Pete K2LCN showed this circuit to me in a video he sent to me:

I modified the circuit to operate on a single supply using rail-to-rail op amps.
A link to the schematic that I used in this video can be found here:

Dino, KL0S put together an EXCELLENT set of annotations to the schematic - well worth a look. Here:
