How to Calculate NMOS as Linear Resistance?
NMOS as Linear Resistance calculator uses Linear Resistance = Length of the Channel/(Mobility of Electrons at Surface of Channel*Oxide Capacitance*Width of Channel*(Gate Source Voltage-Threshold Voltage)) to calculate the Linear Resistance, The NMOS 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 rDS symbol.
How to calculate NMOS as Linear Resistance using this online calculator? To use this online calculator for NMOS as Linear Resistance, enter Length of the Channel (L), Mobility of Electrons at Surface of Channel (μn), Oxide Capacitance (Cox), Width of Channel (Wc), Gate Source Voltage (Vgs) & Threshold Voltage (VT) and hit the calculate button. Here is how the NMOS as Linear Resistance calculation can be explained with given input values -> 0.007961 = 3E-06/(2.2*2.02E-06*1E-05*(10.3-1.82)).
