Abstract :
Effects of threshold gradients at any angle across a die and through active devices on the matching characteristics of current mirrors are discussed. Results show a major improvement but also an unreported limitation in performance of common-centroid layouts. A CAD tool that predicts performance of arbitrary layouts under arbitrary parameter gradients is introduced
