Problem 5.5(b): An NMOS transistor fabricated in a technology for which kn′ = 511 μA/V2 and Vt = 0.4 V is required to operate with a small VDS as a variable resistor by varying the control voltage, VGS. The transistor is sized so that (W/L) = 10. Specify the value of VGS [in Volts] required to achieve a resistance of 0.6 kΩ.
