Enhancement type MOSFET

In these types of devices operate by comprising a channel enhanced in the semiconductor material in which no channel was constructed, they are termed as enhancement-mode MOSFETs. It is just only as easy to construct p-channel versions of these devices like n-channel versions. Indeed CMOS logic ICs contain nothing but these devices, constructed and employed in pairs such that one will be turned off whereas the other is turned on. This is the source of the designation CMOS that is Complementary MOS.

Enhancement-mode MOSFETs have similar benefits and disadvantages as their depletion-mode cousins. Though, when they are constructed as part of an IC rather than as individual devices, they are not readily subject to random static charges. Such types of ICs are constructed with input protection circuitry for any MOSFET input which must be made accessible to external circuitry.
