Abstract: This thesis presents the design methodology for the analog circuits using the genetic algorithm. Matlab is used as a tool to implement the GA (Genetic Algorithm) to analog circuits design problems as it is considered to be easy and robust with powerful features. Several analog circuits like operational amplifier circuits (inverting and non-inverting amplifiers), active filters and multistage amplifier circuits have been designed using the proposed genetic algorithm.

Abstract: As electrical power industry enters the new century, Computer-based Supervisory Control and Data Acquisition (SCADA) systems have been evolved from standalone, traditional compartmental operations into networked architectures that communicate through computer networks across large distances.

Abstract: During the last decade, smart cards have become a widespread digital device. Advantages of smart cards are, for instance, low development costs and thepossibility to obtain a high degree of stability and security. They are frequently used for sensitive applications like money withdrawal or identification systems. The secured identification mechanism of smart cards depends on protocol which can be built in optimized hardware by using a Hash function whereas the heart core for any Hash function is an encryption cipher.
