Consider an n-channel MOSFET with tox = 4.5 nm, ïn = 445 cm2/V·s, Vt = 0.55 V, and W/L = 15. What is the value of k’n ? (6points) Identify the region of operation and find the drain currentin the following four cases. (5 points each) Use ï¥r = 3.9 forSilicon.
a. vGS = 2.0 V and vDS = 2.5 V b. vGS = 2.5 V and vDS = 1.5 V c.vGS = 2.0 V and vDS = 1 V d. vGS = vDS = 2.0 V
