For a typical MOSFET small signal model complete with body e

For a typical MOSFET small signal model complete with body effects, it is known there is a change of drain current of 0.2 mA for achange in V_GS of 0.4 v near the operating point. Determine the transconduction.

Solution

transconductance(g) = ID/VGS = (0.2*10^-3)/0.4 = 0.005

so first option is right answer
