Body Transconductance Solution

Follow our step by step solution on how to calculate Body Transconductance?

FIRST Step Consider the formula

G mb = χ \cdot G m

Next Step Substitute values of Variables

∴

G mb = 0.74 \cdot 1.72mS

Next Step Convert Units

∴

G mb = 0.74 \cdot 0.0017S

Next Step Prepare to Evaluate

∴

G mb = 0.74 \cdot 0.0017

Next Step Evaluate

∴

G mb = 0.0012728S

LAST Step Convert to Output's Unit

∴

G mb = 1.2728mS
