This inverter circuit with transistors provides a voltage of 300 V from a 12 V supply. The current, with the original transistors, is only 55 mA. Transistors must be mounted on heatsinks.
The figure shows how to generate a 60 Hz clock signal for TTL circuits. The circuit is from Radio...
We found this circuit in a 1982 publication. This source allows an adjustment of the output...
This 200 kHz oscillator was found on a 90's EDN. It consumes only 2.8 mW and has CMOS compatible...
