Problem 4 Design the static complementary CMOS implementation of a 2-bit comparator circuit, where we have two inputs A and B (each is 2-bit wide) and the output 0 if A > B and output 1 if A B. Design the circuit for minimum delay (assuming a stage effort of 4) and driving a load of 10 fF. As part of the design you need to determine the width of all transistors You can use the following transistor parameters for...
