Abstract: Adding two binary numbers is a basic operation in binany electronic processing system. Pipelining digital systems has been shown to provide significant performance gains over non-pipelined systems and remains a standard in microprocessor design. The desire for increased performance has seen a push for pipelines. Pipelining is considered to be a good technique for increasing the circuit speed. In this paper, 4-bit conventional adder and 4-bit pipelined adder has been implemented using Cadence virtuoso tool and simulation was performed using the generic 0.18 µm CMOS Technology at 5V. For comparison purposes, various parameters such as delay time, rise time and fall time has been compared which shows that pipelined adders are more efficient in terms of speed, power and throughput.
