What is the condition to use the MOSFET as a linear resistor?

When you slowly increase the gate voltage the MOSFET slowly starts conducting by entering the linear region where it starts developing a voltage across it which we call V _DS . In this region, the MOSFET acts as a resistance of finite value.

How to Calculate MOSFET as Linear Resistance?

MOSFET as Linear Resistance calculator uses Linear Resistance = 1/Conductance of Channel to calculate the Linear Resistance, The MOSFET as linear resistance acts as a variable resistor in the linear region and as a current source in the saturation region. Unlike a BJT, to use a MOSFET as a switch, you need to operate within the linear region. Linear Resistance is denoted by R_ds symbol.

How to calculate MOSFET as Linear Resistance using this online calculator? To use this online calculator for MOSFET as Linear Resistance, enter Conductance of Channel (G) and hit the calculate button. Here is how the MOSFET as Linear Resistance calculation can be explained with given input values -> 0.000167 = 1/0.006.
