Found in a 90s Siliconix documentation, this high voltage power supply uses components from that time. MOSFETs can be current equivalents.
This circuit was found in an 80's EDN. The circuit uses a current common CMOS, the 4093 powering...
We found this circuit in a 90's European schematic. The circuit can be implemented with almost any...
We found this circuit in a 70s publication. Transistors are general-purpose types of the time. The...
