How to Evaluate Ohmic Region Drain Current of FET?

Ohmic Region Drain Current of FET evaluator uses Drain Current FET = Channel Conductance FET*(Drain Source Voltage FET+3/2*((Surface Potential FET+Drain Source Voltage FET-Drain Source Voltage FET)^(3/2)-(Surface Potential FET+Drain Source Voltage FET)^(3/2))/((Surface Potential FET+Pinch OFF Voltage)^(1/2))) to evaluate the Drain Current FET, Ohmic Region Drain Current of FET is the drain current that flows when the drain-to-source voltage is small and the gate voltage is zero. In this region, the drain current is proportional to the drain-to-source voltage and the channel conductance of the FET. In a voltage amplifier, the ohmic region drain current of an FET is used to generate a voltage gain. The FET is biased in the ohmic region so that it behaves like a linear resistor. The input voltage is applied to the gate of the FET and the output voltage is taken from the drain of the FET. The voltage gain of the amplifier is determined by the channel conductance of the FET and the load resistance. Drain Current FET is denoted by I_d(fet) symbol.
