This circuit is from the Motorola Linear Databook of 1990 and can be implemented with other operational amplifiers. The power supply must be symmetrical.
This circuit was obtained in an old magazine from the 1970s. The circuit can still be assembled with...
This power oscillator uses an LM380 amplifier. We found it in old English documentation. The C3...
In the figure we show a simple way to use a zener diode to protect a load against overvoltage. The...
