Body Effect on Transconductance Formula

Body Transconductance = Change in Threshold to Base Voltage*Transconductance
g_mb = Χ*g_m

What is voltage gain?

The difference between the output signal voltage level in decibels and the input signal voltage level in decibels; this value is equal to 20 times the common logarithm of the ratio of the output voltage to the input voltage.
