Various measurements are made on an NMOS amplifier for which the drain resistor RD is 20 k . First, DC measurements show the voltage across the drain resistor, VRD, to be 2 V and the gate-to-source bias voltage to be 1.2 V. Then, ac measurements with small signals show the voltage gain to be 10 V/V. If the process transconductance parameter is 50 A/V2, what is the MOSFET s W/L?
