Obtained from an Electronic Engineering of the 90s, these circuits can be applied to almost any operational amplifier. Signal shapes are given next to the diagram.
We found this circuit in an old American documentation, from 1971, but the component used is still...
This configuration can be found in several articles on this site. The one shown in the diagram is from...
The operational amplifier used in this circuit is no longer common on the market, as the circuit is...
