Question

Question 5. (12 points) 1) (3 points) Apply "bubble pushing" and redraw the circuit (a buffer can be replaced with a wire). 2) . (3 points) What is the boolean expression for the obtained circuit? And Sketch a K-map. 3) . (3 points)What is the propagation delay and contamination delay of the original circuit? Assume the inverter gate has a propagation delay of 15ps and a contamination delay of 10 All other gates have a propagation delay of 30ps and a contamination delay of 20ps. (wire delay is negligible) ps.
