7.6 Various measurements are made on an NMOS amplifier for which the drain resistor R D is 20 k. First, dc measurements show the voltage across the drain resistor, VRD, to be 1.5 V and the gate-to-source bias voltage to be 0.7 V. Then, ac measurements with small signals show the voltage gain to be –10 V/V. What is the value of V t for this transistor? If the process transconductance parameter kn is 200 μA/V2, what is the MOSFET’s W/L?
