Bio-inspired Approach to Microwave Circuit Design

Abstract

The article describes a bio-inspired approach to the structural and parametric design of microwave circuits based on a genetic algorithm (GA), which permits algorithmic environment in the field of genetic search for solving NP complete problems, in particular, structural-parametric synthesis of a microwave amplifier. The article is aimed at finding ways of structure-parametric synthesis of microwave modules based on a bio-inspired theory. Scientific novelty of the research lies in the development of a modified genetic algorithm for a bio-inspired automated structural and parametric synthesis of microwave modules. The problem statement in the paper is as follows: to optimize the synthesis of passive and active microwave circuits by using a modified GA. The fundamental distinction of a new approach from the known is the use of new modified genetic structures in bio-inspired automatic structural and parametric synthesis, moreover, a new method for calculating a microwave amplifier based on modified GA is presented in the work. Thus, the problem of creating methods, algorithms and software for automated structural synthesis of microwave modules is currently of special actuality. The solution of the problem will improve the quality characteristics of the designed devices; reduce the time and cost of design and lower the requirements for implementation qualifications.
