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.

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 op amp-based current sensing circuit described here is not new, it has been around for some time, but with very little discussion of the circuit itself. Somewhere along the line it was informally ...
