I've been struggling with how to solve this problem on F04 delay: Approximate the F04 delay on the following devices: 1)2-Input AND 2)3-Input OR 3)2-Input XOR I know how to figure out the CMOS implementation but I don't understand how to calculate the F04. Secondly: calculate the F04 for a 4 bit ripple adder. I have the logic gates for it but like i said I don't know how to calculate the F04. Any help would be appreciated!!
