The Extension of Linear Coding Method for Automated Analog Circuit Design

Encoding method is one of the key factors of evolutionary design of analog circuit. Due to the adaptability, convenience and relatively short length of linear coding method, it has been widely used for automation of analog circuit design. Evolutionary design of analog circuits, which is not limited to traditional knowledge, could generate circuits with novel structures and parameters. The novel structures provide more possible solutions for fault-tolerance design of analog circuits. While, the current linear coding method based on five connection ways limits the number of possible circuit structures. So in this paper, we improve the existing linear coding method by expanding the instruction set. The experimental results show that the improved linear coding method can generate richer circuit structures, and it opens up a new way for the fault-tolerance design of analog circuits.
