Last Updated on September 4, 2023 by Paganoto

Design of Ripple Carry Adders – CSE IIT Kgp

Each full adder requires three levels of logic.In a 32-bit [ripple carry] adder, there are 32 full adders, so the critical path (worst case) delay is 31 * 2(for carry propagation) + 3(for sum) = 65 gate delays.
