In Part 1 of this five-part series, we examined FET voltage controlled resistors, basic voltage controlled resistor circuits, and a balanced or push pull voltage controlled resistor (VCR) circuit.

The source voltage of a P-channel device is stationary when the device operates as an HS switch. Conversely, the source voltage of an N-channel device used as an HS switch varies between the low side ...

Find a downloadable version of this story in pdf format at the end of the story. TYPICAL HIGH-SIDE, n-channel, hot-swap “soft-switch” systems use a charge pump to drive the gate of an external MOSFET ...

The circuit was designed to produce high quality and powerful audio amplifier that would provide 60W-90W power output. MPSA43 – NPN high voltage transistor with low current and high voltage used for ...
