Question: an nbit comparator compares two nbit numbers a and b...

Question details

An N-bit comparator compares two N-bit numbers A and B and indicates whether the numbers are equal or which of the numbers is greater. Hence there are two N-bit inputs to the comparator A and B, and three one-bit outputs, A < B, A , A > B a) Design a basic cell of a 1-bit comparator using static CMOS gates that allows modular expansion of the comparator to N-bits. Note that N can be a large number. (10 pts) b) Using the basic cell from part a, design a 4-bit comparator. (10 pts)
