5.20 An NMOS transistor, operating in the linear-resistance

region with = 50 mV, is found to conduct 50 µLA for

-0.8 V and 100 μA for 1.2 V. What is the apparent

value of threshold voltage V? If=500 A/V, what is the

device WII. ratio? What current would you expect to flow

with = IV and = 0.2 V? If the device is operated

IV. at what value of will the drain end of

the MOSFET channel just reach pinch-off, and what is the

corresponding drain current?
