Automation of Bandgap Voltage Reference Optimization using Vectorized Coarse-Fine Grid Search

In this paper, a grid search approach is used to automate the optimization of a bandgap reference circuit. A bandgap reference automated synthesis algorithm is vectorized to enable the synthesis of multiple design points in parallel. The synthesis algorithm maps each design point to its corresponding specifications. Using this vectorized implementation, it becomes possible to quickly generate large datasets spanning the whole design space. The dataset is filtered to find the points that meet required specifications. Interpolation is then used around these points to generate finer grids. A final search in those grids is then carried out to find the optimal design point. This approach effectively enables the designer to find an optimal design point satisfying his desired specifications effortlessly.
