Question

$If an n-channel enhancement MOSFET is biased in common source mode such that its gate to source voltage V_{G S} = 2 V and V_{T} = 1 V . the value of trans conductance is______m ℧ (Neglecting channel length modulation ).$
$V_{D S} = 3 V, μ_{n} C_{o x} (\frac{W}{L}) = 0.5 m A / V^{2}$

0.5

Open in App

Solution

The correct option is A 0.5
$∵ V_{D S} > V_{G S} - V_{T}$

$thus the device is in saturation region g_{m} = \frac{μ_{n} C_{o x} W}{L} (V_{G S} - V_{T}) = 0.5 \times 10^{- 3} = 0.5 m ℧$
