P R O B LEM II. 6 a) Express F¯ in a simplified sum-of-products form given that F = AB¯+CD¯. b) Implement the logic function F = AB¯+CD¯ with an NMOS digital logic circuit that obeys the static discipline defined by the low-level and high-level logic thresholds VIL = VOL = VL and VIH = VOH = VH, respectively. Assume the supply voltage is VS, and that the on-state resistance of the NMOS transistors is RON. Determine the lowest value of the pull-up resistor RPU for which the circuit will obey the static discipline in terms of RON, VS, VL, and VH; not all variables need appear in your answer. c) Implement the logic function F = AB¯+CD¯ with a CMOS digital logic circuit. (Hint: make use of the result from part (a). ) d) Suppose that the NMOS and CMOS circuits above drive a capacitance CL. Assume that the on-state resistance of both the PMOS and NMOS transistors is RON. For both the NMOS and CMOS circuits determine the worst-case output rise time. For the purpose of this problem, assume that the worst-case output rise time is the time the output takes to go from 0 V to VH. Sketch the form of the output for both the NMOS and the CMOS circuit. e) Suppose that the inputs are arranged such that B = 1, C = 0, and D = 1, and that a 0−V to 5−V square-wave signal is applied to the input A. Assume the square wave cycle time is T, and that T is large enough so that the output comes close to its steady state value for both falling and rising transitions. Under these conditions, compute the power consumed by the CMOS and NMOS circuits when driving the capacitance CL load.

5. (7 points) In this problem we'll complete the first few steps of solving a differential equation in context using eigenvectors and eigenvalues. Suppose a car rental company has two locations, location P and location Q. When a customer rents a car at one location, they have the option to return it to either location at the end of the day. Market research determines that 80% of the cars rented at location P are returned to P and 20% are returned to Q. 40% of the cars rented at location Q are returned to Q and 60% are returned to P. (a) Suppose that there are 1000 cars at location P and no cars at location Q on Monday morning. How many cars are there at location P and Q respectively at the end of the day on Monday? (b) How many cars are at each location, P and Q, at the end of the day on Tuesday? (b) How many cars are at each location, P and Q, at the end of the day on Tuesday? (c) If we let Pk and Qk be the number of cars at locations P and Q, respectively, at the end of day k, then we have Pk+1 = 0.8Pk + 0.6Qk Qk+1 = 0.2Pk + 0.4Qk Explain why this system of equations appropriately models the given situation. (d) Write the above system of equations as a matrix equation. (e) Suppose that v→ = [3 1] and w→ = [−1 1]. Compute Av→ and Aw→ to show that v→ and w→ are eigenvectors of A (where A is the coefficient matrix you found in part (d)). (f) What are the associated eigenvalues? Let λ1 be the eigenvalue associated with v→ and λ2 be the eigenvalue associated with w→. (g) We said that 1000 cars are initially at location P and none at location Q. This means that the initial vector describing the number of cars is [P0 Q0] = [1000 0] Write this initial condition as a linear combination of v→ and w→. To do this, consider [P0 Q0] = c1v→ + c2w→ and solve for c1 and c2. Then, substitute those values back into this matrix equation. [P0 Q0] = …−−−−−−[3 1]+…−−−−−−−[−1 1]5.
