Variation-aware Analog Circuit Design via Contextual Modeling and Robust Optimization

Year: 2025

Type: article

Abstract: Robust analog circuit design is becoming increasingly challenging due to process, voltage, and temperature (PVT) variations at advanced technology nodes. In this article, we formulate analog circuit synthesis as a robust optimization problem, and propose a Contextual Robust OptimiZAtion (CROZA) method for variation-aware analog circuit design. The proposed method uses Contextual Gaussian process to model both the design parameters and perturbation parameters, and a hybrid strategy of adversarially robust optimization and stochastically perturbed robust optimization to find robust solutions. Compared to state-of-the-art methods, our proposed approach achieves significant simulation and runtime speedups while delivering superior optimization results.
