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.

The final part of this series will start with bias servo circuits for automatic set up. The FETs pinch off or threshold voltage can vary widely for the same part number. Depending on the fabrication ...

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 ...
