This formula uses 3 Variables
Variables Used
Overdrive Voltage - (Measured in Volt) - Overdrive voltage is a term used in electronics and refers to the voltage level applied to a device or component that exceeds its normal operating voltage.
Drain Current - (Measured in Ampere) - Drain current is the current that flows between the drain and the source terminals of a field-effect transistor (FET), which is a type of transistor commonly used in electronic circuits.
Transconductance - (Measured in Siemens) - Transconductance is defined as the ratio of the change in the output current to the change in the input voltage, with the gate-source voltage held constant.
STEP 1: Convert Input(s) to Base Unit
Drain Current: 0.08 Milliampere --> 8E-05 Ampere (Check conversion ​here)
Transconductance: 0.5 Millisiemens --> 0.0005 Siemens (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Vov = (2*id)/gm --> (2*8E-05)/0.0005
Evaluating ... ...
Vov = 0.32
STEP 3: Convert Result to Output's Unit
0.32 Volt --> No Conversion Required
0.32 Volt <-- Overdrive Voltage

Overdrive Voltage = (2*Drain Current)/Transconductance
Vov = (2*id)/gm

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.

How to Calculate Overdrive Voltage?

Overdrive Voltage calculator uses Overdrive Voltage = (2*Drain Current)/Transconductance to calculate the Overdrive Voltage, The overdrive voltage represents the voltage difference between the gate and the threshold voltage. Overdrive Voltage is denoted by Vov symbol.
