Question

5.14 ° When a MOSFET is operated well into the tri- ode region, it behaves much like a voltage-controlled re- sistor whose resistance is inversely proportional to vGs. The device manufacturer can set the proportionality con- stant K by controlling the width-to-length ratio W/L, as indicated by Eq. (5.2). What value of W/L would be required to make a MOSFET whose channel resis- tance changes from 1 kΩ to 200 Ω as uGS 1s change
