Found in American documentation from the 90s, this circuit uses components that are still common today. The 15 V power supply must be symmetrical.
In the figure we have a bistable multivibrator using an operational one. The circuit is from old...
The circuit shown here is a CCO. The frequency here depends on the current through the...
This circuit uses a capacitor to momentarily reduce the anode-to-cathode voltage of the SCR for...
