Manual optimization of parameters in analog integrated circuit (IC) design is a laborious and uncertain task, with no guarantee of achieving a good result. This paper presents an application of the blended distribution estimation evolutionary algorithm for parameter optimization in a dual-output voltage reference. To enhance the convergence speed and optimization effectiveness of automated IC design, such as voltage references, a blended distribution estimation evolutionary algorithm and an out-of-range (OOR) function based on performance ranking are proposed. The proposed methodology is demonstrated to significantly outperform the manual solution, with TC1, TC2, and power consumption improving by 34.97%, 17.08%, and 13.35%, respectively. Moreover, FoM1and FoM2are improved by 270.69% and 185.29%, respectively.
