यदि VDS < Vgs - Vt है
तो MOSFET सक्रीय क्षेत्र (रैखिक क्षेत्र) में है।
अपवाह धारा निम्नवत है
\({{I}_{D}}=\frac{1}{2}{{\mu }_{n}}{{C}_{ox}}\frac{W}{L}\left( 2\left( {{V}_{gs}}-{{V}_{t}} \right){{V}_{DS}}-V_{DS}^{2} \right)\)
यदि VDS ≥ Vgs - Vt है
संचालन का मोड क्षेत्र में संतृप्ति है।
\({{I}_{D\left( sat \right)}}={{\mu }_{n}}{{C}_{ox}}\frac{W}{2L}{{\left( {{V}_{gs}}-{{V}_{t}} \right)}^{2}}\)
Additional Information
संतृप्ति क्षेत्र में
\({{g}_{m}}=\frac{d{{I}_{{{D}_{sat}}}}}{d{{V}_{GS}}}=\frac{W}{2L}{{\mu }_{n}}{{C}_{ox}}2\left( {{V}_{GS}}-{{V}_{T}} \right)=\frac{W}{L}{{\mu }_{n}}{{C}_{ox}}\left( {{V}_{GS}}-{{V}_{T}} \right)\)
