![]() The D-MOSFET can be ‘N-channel D-MOSFET’ or ‘P-channel D-MOSFET’ depending on the channel being used. This is why the D-MOSFET can work in both depletion and enhancement mode. It will result in increasing the current flow between drain and source. If Gate and source is connected in forward bias and the V GS is increased, more majority carriers will get induced in the channel and its width will increase. At this point, the D-MOSFET stops conduction and this V GS voltage is known as V TH threshold voltage. It reduces the width of the channel until it completely vanishes. Due to this reason, it is also known as “Normally ON” MOSFET.Ĭonnecting the gate-source terminal in reverse bias will deplete the channel of the charge carrier thus the name depletion MOSFET. Therefore, it can conduct current between source and drain when the gate-source voltage V GS = 0 volts. In other words, it has a channel even when there is no voltage applied to it. The Depletion type MOSFET or D-MOSFET is a type of MOSFET that has a channel constructed during the process of fabrication.
