This circuit with the XR2206 IC squares the value of a voltage. The circuit was published in the April 1978 issue of Radio Electronics magazine and should be powered by a symmetrical 15 V source.
The presented circuit uses an operational amplifier that is uncommon nowadays, but it can be...
This circuit is powered by only 3 V and can flash white LEDs from 3.2 to 3.6 V, as it includes a voltage...
