Gmb = χ*Gm
This formula uses 3 Variables
Variables Used
Body Transconductance - (Measured in Siemens) - Body Transconductance is the product of transconductance and back-gate transconductance parameter.
Back-gate Transconductance Parameter - Back-gate transconductance parameter generally its value lies between 0.1 to 0.3 in a transistor.
Transconductance - (Measured in Siemens) - Transconductance is the ratio of the change in current at the output terminal to the change in the voltage at the input terminal of an active device.
STEP 1: Convert Input(s) to Base Unit
Back-gate Transconductance Parameter: 0.74 --> No Conversion Required
Transconductance: 1.72 Millisiemens --> 0.00172 Siemens (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Gmb = χ*Gm --> 0.74*0.00172
Evaluating ... ...
Gmb = 0.0012728
STEP 3: Convert Result to Output's Unit
0.0012728 Siemens -->1.2728 Millisiemens (Check conversion here)
FINAL ANSWER
1.2728 Millisiemens <-- Body Transconductance

What is the use of transconductance in MOSFET?

Transconductance is an expression of the performance of a bipolar transistor or field-effect transistor (FET). In general, the larger the transconductance figure for a device, the greater the gain(amplification) it is capable of delivering, when all other factors are held constant.
