[#215] 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 be significant, the MOSFET behaves as a
Correct Answer
(C) Current source with finite output impedance
