Digital Integrated Circuits Design Based Genetic Algorithm

Abstract

Genetic algorithms (GAs) are search and optimization techniques that are used in engineering applications like systems optimization equation solving and electronic circuits design and synthesis. genetic algorithms are used in the design and synthesis of fixed topology electronic circuits. Two types of digital integrated circuits are considered, CMOS NAND circuit and CMOS NOR circuit. Several gate circuits are designed and synthesized to obtain the best value of (W/ L) s for the transistors in the circuits. These aspect ratios minimize the required circuit total chip area while still satisfying the logic function of the circuit with minimum deviation from the ideal characteristics. The resultant gate structures have less aspect ratio than those resulting from the traditional design techniques.
