Critical Voltage evaluator uses Critical Voltage = Critical Electric Field*Electric Field Across Channel Length to evaluate the Critical Voltage, The Critical Voltage formula is defined as the drain-source voltage at which the critical effective field is reached. Critical Voltage is denoted by Vx symbol.
