An n-channel enhancement mode MOSFET is biased at V

_{GS}> V_{TH}and V_{DS}> (V_{GS}- V_{TH}), where V_{GS}is the gate-to-source voltage, V_{DS}is the drain-to-source voltage and V_{TH}is the threshold voltage. Considering channel length modulation effect to be significant, the MOSFET behaves as a2
