Design and Implementation of 4-bit and 8-bit KSA in 18nm FinFET Technology

Project Code :TVPGBE142


The objective is to compute-a small group of intermediate prefixes, then a large group of-prefixes, and so on, until all of the carry bits have been computed. Parallel-prefix structures have been discovered to appeal to adders due to their logarithmic latency.


This paper is implemented in the 18nm FinFET model's technology node. It has a high PDP  (Power-Delay Product )because it operates at a faster rate than its competitors. The adder is designed and built for bit lengths of 4 and 8, with random input data simulations used to evaluate its operations. Criteria such as power, performance, area, gate count,. Every block used to construct the adder is inspected, and the results are graphically shown. In order to properly examine the parameters, the acquired data is tabulated.  All the designs are implemented  in cadence virtuoso.

Index Terms—Ripple Carry Adder (RCA), Carry Look Adder (CLA), Carry Increment Adder (CIA), Parallel Prefix Adder (PPA), Kogge-Stone Adder (KSA), FinFET.
