Why depletion mosfet is known as normally-on mosfet, Electrical Engineering

Assignment Help:

Q. Why depletion MOSFET is known as "normally-on MOSFET" ? Draw the symbol of n-type and p-type depletion MOSFET.

In depletion type MOSFET the drain current flows even when VGS is made zero.

Also it can have drain current in either the depletion mode or the enhancement mode.  Such a device is known as "normally-on MOSFET".

The drain current is given by the formula:

                      ID = IDSS [1-   VGS/VGS (OFF)] ^2
