This type of power MOSFET is widely used in digital computers. The construction of enhancement type power MOSFET is shown in figure above .This is an n-channel device.However as seen in the figure,the p-substrate extends right up to the silicon dioxide layer.Thus there is no n-channel between drain and source. The above figure shows the [...]

Drain characteristics of an n-channel MOSFET is shown in figure below. VGS can be positive and negative.The characteristics for p-channel are similar to the above figure excepts signs of current and voltage are reversed. The transconductance curve(transfer characteristics)of depletion type MOSFET is shown in figure below. This characteristcs shows the variation of ID with VGS.IDSS [...]
