Question

A depletion type N-channel MOSFET is biased in its linear region for use as a voltage controlled resistor. Assume threshold voltage VTH=−0.5 VV_{TH} = -0.5\text{ V}, VGS=2.0 VV_{GS} = 2.0\text{ V}, VDS=5 VV_{DS} = 5\text{ V}, W/L=100W/L = 100, Cox=10−8 F/cm2C_{ox} = 10^{-8}\text{ F/cm}^2 and μn=800 cm2/V-s\mu_n = 800\text{ cm}^2/\text{V-s}. The value of the resistance of the voltage controlled resistor (in Ω\Omega) is __________.
