Like the previous JFET tutorial, MOSFETs are three terminal devices with a Gate, Drain and Source and both P-channel (PMOS) and N-channel (NMOS) MOSFETs are available. The main difference this time is that MOSFETs are available in two basic forms:.
Depletion Type: The transistor requires the Gate-Source voltage, (VGS) to switch the device "OFF". The depletion mode MOSFET is equivalent to a "Normally Closed" switch.
Enhancement Type: The transistor requires a Gate-Source voltage, (VGS) to switch the device "ON". The enhancement mode MOSFET is equivalent to a "Normally Open" switch.
Depletion Type: The transistor requires the Gate-Source voltage, (VGS) to switch the device "OFF". The depletion mode MOSFET is equivalent to a "Normally Closed" switch.
Enhancement Type: The transistor requires a Gate-Source voltage, (VGS) to switch the device "ON". The enhancement mode MOSFET is equivalent to a "Normally Open" switch.

Mosfet work both depletion and enhancement mode but FET works only depletion mode.
