Homework 04 SolutionsECE 429, Spring 20161.(20 points)Consider the design of a pass-transistor logic circuitF=A B+BC.A. Assume that all the signalsA,B,C, and their complements are availablebut can only be used to control the gates of the transistors. All the inputsconnected to the diffusions of the transistors should be connected to eitherVDDor GND. Design the transistor-level circuit.B. Simplify the circuit by removing redundant PMOS/NMOS transistors.
ECE 429 – Introduction to VLSI Design, Spring 201622.(20 points)Consider the design of a domino logic circuitF= (A+B)(C+D)with the clock signalφ.A. Assume that the signalsA,B,C, andDare available and monotonicallyrising during evaluation. Design the transistor-level circuit.B. Assume that the signals change as in the following figure. Show the wave-forms of all the outputs including the intermediate ones similar to Fig. 6.28(b) on the textbook.Answer:
