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 isQuestions Asked from IC Basics and MOSFET (Marks 2)
