Question

$\text{An n-channel MOSFET is biased with}{V}_{GS}=2V,V_{DS}=1V\text{and the value of threshold voltage for the MOS transistor is 1.5 V. Then MOSFET is operating in}$

• A. Cutoff region
• B. Linear region
• C. None of the above
• D. Saturation region

Answer 1

The correct option is D Saturation region

$V_{GS}-V_t=2-1.5=0.5V$
$\text{and}{V}_{DS}=1V$
$\therefore V_{DS}>V_{GS}-V_T$
Hence, MOSFET is in saturation region.
