2. An NMOS transistor, operating in the linear resistance region, with VDS = 50 mV, is found to conduct 25 uA for VGS-1V and 50 uA for VGS-1.5V. a. What is the apparent value of the threshold voltage V₂? b. If kn 50 uA/V2, what is the device W/L ratio? c. What current could you expect to flow with VGS = 2V and VDs= 0.1V? d. If the device is operated what VGS=2V, at what value of VDs will the drain end of the MOSFET channel just reach pinch-off, and what is the corresponding drain current?
