In the figure we have the way to implement a power zener diode. The voltage depends on the zener, and the maximum current of the transistor.
This circuit combines a low-offset and a high-speed operational amplifier. The circuit was found in...
We found this circuit in the 1983 Radio Electronics Special projects magazine. The components are...
This power oscillator uses an LM380 amplifier. We found it in old English documentation. The C3...
