**Question:**An NMOS single transistor common source amplifier is biased with \( I_D = 20 \, \text{mA} \). If the external bias conditions are changed so that \( I_D \) decreases to 12 mA, we expect an effect upon the transconductance parameter:- \( g_m \) increased by a factor 1.667- \( g_m \) reduced by a factor 0.77- \( g_m \) reduced by a factor 0.6- \( g_m \) unchanged**Explanation:**The image displays a question regarding the impact of changing the drain current (\( I_D \)) on the transconductance (\( g_m \)) of an NMOS common source amplifier. The drain current is initially set at 20 mA and then reduced to 12 mA. The possible changes to the transconductance are provided as multiple-choice options. The correct answer indicated is that \( g_m \) increased by a factor of 1.667.

An NMOS single transistor common source amplifier is biased with ID = 20 mA. If the external bias conditions are changed so that Ip decreases to 12 mA, we expect an effect upon the transconductance parameter: gm increased by a factor 1.667 gm reduced by a factor 0.77 gm reduced by a factor 0.6 8m unchanged
