Discrete audio amplifier basics – Part 2: JFETs, MOSFETs and other circuit configurations

JFETs are, almost invariably, depletion mode devices, which means that there will be some drain current at a zero-applied gate-source potential. This current will decrease in a fairly linear manner as ...

P-Channel Power MOSFETs Approach N-Channel Performance

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 ...
