Response to the following :
Various measurements are made on an NMOS amplifier for which the drain resistor RD is 20 kΩ. 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 Vt for this transistor?
If the process trans conductance parameter k_ n is 200 μA/V2, what is the MOSFET's W/L?
