A negative-correlation redundancy design model for automated synthesis of analog circuits

The negative-correlation redundancy approach is a novel way for fault-tolerant design of analog circuits under uncertain faults. One of its key factors is the design of negative-correlation redundancy evolutionary model. In this paper, we propose a novel negative-correlation redundancy evolutionary design model. In order to improve the scalability of this model, DE_SR algorithm is proposed. Experimental results on analog low-pass filters show clearly that this novel model is effective and feasible. Compared with the existing negative-correlation redundancy evolutionary model named ENCF, our model has a lower computational complexity and higher search efficiency, and it have better on large-scale problems of circuit synthesis.
