The key performance of many analog circuits is directly related to accurate capacitor ratios. It is well known that capacitor ratio precision is greatly enhanced by paralleling identical size unit capacitors in a common-centroid geometry. In this paper, a general algorithm for fitting arbitrary capacitor ratios in a common-centroid unit-capacitor array is presented. …
