Both MOSFET types described below can be of p- or n-type (also known as p-channel and n-channel), but n-channel devices are the most prevalent. MOSFETs can operate in two mode types: depletion mode (D ...

Typically, a thin layer of oxide insulation is used to prevent current from flowing between the gate and a conductive channel in the semiconductor substrate. There are two basic types of MOSFET RF ...
