Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

Determine VGS and VDS for the E-MOSFET circuit in the figure. Assume this particular MOSFET has minimum values of ID(on) = 200mA at VGS = 4V and VGS(th) = 2V. We then calculate ID for VGS = 3.13V.

Many offline-powered systems today need a low-voltage bias supply to power its control circuitry and intelligence. In some cases, bias supply outputs are not required to be isolated from the AC mains, ...

This file type includes high resolution graphics and schematics when applicable. In some situations, it becomes necessary to drive a MOSFET (or IGBT) with a voltage that’s lower than its ...

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 ...
