An evolutionary technique for a linear analog circuit state recognition is presented in this paper. Transfer function zeros, poles and its amplification coefficient are determined by means of differential evolution. Time responses to a unit step stimulus for the circuit under test and for the evaluated phenotype are compared during the fitness calculation. Absolute response error of phenotype is minimized during evolution cycles to achieve the desired transfer function. The proposed method can be used for a linear analog circuit diagnosis, especially during the design stage when accurateness of diagnose is more critical than computations time.
