The drain of an n-channel MOSFET is shorted to the gate so that V

_{GS}= V_{DS}. The threshold voltage (V_{T}) of MOSFET is 1 V. If the drain current (I_{D}) is 1 mA for V_{GS}= 2 V, then for V_{GS}= 3 V, I_{D}is2

When the gate-to-source voltage (V

_{GS}) of a MOSFET with threshold voltage of 400 mV, working in saturation is 900 mV, the drain current is observed to be 1 mA. Neglecting the channel width modulation effect and assuming that the MOSFET is operating at saturation, the drain current for an applied V_{GS}of 1400 mV is3

For an n-channel enhancement type MOSFET, if the source is connected at a
higher potential than that of the bulk (i.e. V

_{SB}> 0), the threshold voltage V_{T}of the MOSFET will4
