1 1 vote The drain current of a MOSFET in saturation is given by $I_{D}=K\left(V_{G S}-V_{T}\right)^{2}$ where $K$ is a constant. The magnitude of the transconductance $g_{m}$ is $\frac{K\left(V_{G S}-V_{T}\right)^{2}}{V_{D S}}$ $2 K\left(V_{G S}-V_{T}\right)$ $\frac{I_{d}}{V_{G S}-V_{D S}}$ $\frac{K\left(V_{G S}-V_{T}\right)^{2}}{V_{G S}}$ BJT and MOSFET Amplifiers gate2008-ec mosfet analog-circuits numerical-answers + – admin 318 views answer comment Share Follow Add Sync Questions Print 0 reply Please log in or register to add a comment.
