DESIGN OF ELECTRONIC CIRCUITS FOR OPTIMAL PRODUCTION YIELD

Abstract

The new methods of electronic circuit design make possible not only to determine the production yield, but also to calculate new nominal element values and optimal tolerances. The design methodology is called design centering and tolerance assignment. The elaboration of methods demands further development of the sensitivity and tolerance theory of electronic circuits. To solve the task. Monte Carlo simulation and optimization methods are applied. The paper deals with the development of the design concepts for optimal production yield and presents algorithms to determine new nominal element values, tolerances and production specification. Reference is made to the computer programs developed in the Institute of Communication Electronics of the Budapest Technical University and successfully used in industry. The efficiency of the new design methodology is illustrated by examples of LC filters.
