Consider an n-channel MOSFET having width W, length L, electron mobility in the channel
$$\mu_n$$ and oxide capacitance per unit area $$C_{ox}$$. If gate-to-source voltage VGS=0.7 V, drain-to source
voltage VDS=0.1V, $$\left(\mu_nC_{ox}\right)\;=\;100\;\mu A/V^2$$, threshold voltage VTH=0.3 V and (W/L) = 50,
then the transconductance gm (in mA/V) is ___________.

An n-channel enhancement mode MOSFET is biased at VGS > VTH and VDS > (VGS - VTH), where
VGS is the gate-to-source voltage, VDS is the drain-to-source voltage and VTH is the threshold
voltage. Considering channel length modulation effect to be significant, the MOSFET behaves
