Step 1 of 2 5.004E NMOS transistor is operating at the edge of saturation, with an overdrive voltage and drain current Since the NMOS transistor works in the edge of saturation, the drain source voltage is equal to the overdrive voltage, = If the overdrive voltage, is doubled, the drain source voltage, should become twice the value of former overdrive voltage to maintain operation at the edge of saturation. Therefore, the voltage changed to Step 2 of 2 The relation of the drain current with the overdrive voltage is, (1) The new drain current when is doubled is, (2) Divide equation (1) by equation (2). Therefore, the new value of drain current is
