1. Consider the pictured RC network:10k10k10k10k5p15p5pa.Write an algebraic expression for the Elmore delay. b.What is the corresponding time constant? 2. Consider an inverter with a size 15 P and a size 5 N. a.What are the logical efforts for rising and falling transitions? 3. Given up to 8 size 4 PMOS and 8 size 2 NMOS transistors and inputs A, B, C, and !C: c. Build a 2:1 multiplexer. Use Connect data inputs A and B to terminals A and D (B and C would also work) Connect select inputs C and !C to the unused terminals A B C D A B C D A B C D A B C D B D Y A C A C A B C D B D Y (a) (c) (e) (b) (d) (f)
d.Write its algebraic function in either Boolean or HDL. e.Compute the logical efforts of the four inputs.
