The research of parameter optimization design method for analogy circuit [analog circuits]

This paper proposes an analog circuit tolerance distribution method, based on the orthogonal table, which reduces the parameter design computation requirements. In the tolerance distribution, an improvement of the stability of the output characteristics of the circuit is achieved at the cost of an increase of the cost of the circuit. In order to enhance the stability of circuit output characteristics while keeping the cost unchanged, this paper proposes a parameter optimization design method after the completion of the tolerance design.
