Parametric Analysis of 4-Bit Adder/Subtractor

Amrita Shukla; Prof. Sandip Nimade; Prof. Vikas Gupta

Adders are key components in digital design, performing not only addition operations, but also many other functions such as subtraction, multiplication and division. Adders of various bit widths are frequently required in Very Large-Scale Integrated circuits (VLSI) from processors to Application Specific Integrated Circuits (ASICs).This paper deals with layout of 4-bit full adder/subtractor. It can be use as a adder circuit for 4bit addition and also as a subtractor for subtraction with a clock signal. The result of simulation of adder/subtractor layout is in Microwind2.
