(25 points) Consider an NMOS transistor with L-0.18 um and W-2 um. The process technology is specified to have Cox 8.6 fF/um2, Hn = 450 cm2/V s, and Vin 0.5 V. a) Find VGs and VDs that result in the MOSFET operating at the edge of saturation with ID 100 uA. b) If VGs is kept constant, find Ip when VDs is reduced to 0.06 V
4.3.5. Using eqs (1) to (5) and assuming um()-0 and L 0, derive the transfer function Ga(s) between Ta(s), the Laplace transform of the torque disturbance Tat), and (s), the Laplace transform of the angular velocity of the rotor omlt).
Problem 3 An n-channel MOSFET with L=1 um, W=3 um, tox=20 nm, V=0.7 V, and an effective electron mobility in the channel of 650 cm/V-s. a) If the MOSFET is biased with VG-V=3V, and Vp=2V, what is the drain current and transconductance of this MOSFET? b) Assume long channel theory is valid, what are (i) the velocities of channel carriers at the source and drain? (ii) the output resistance of the MOSFET? c) Plot channel conductance (ga) versus VG for...

1 pts A land surveyor just starting in private practice needs a van to carry crew and equipment. He can lease a used van for $8000 per year, paid at the beginning of each year, in which case maintenance is provided. Alternatively, he can buy a used van for $16,000 and pay for maintenance himself. He expects to keep the van for 3 years, at which time he would sell it for an anticipated $3500. Given a MARR of 6%,...
