Abstract
Circuit designs and methods are provided for matching device characteristics for, e.g., analog or mixed-signal semiconductor integrated circuit designs. In particular, circuit layout patterns and layout methods are provided which enable precise or proportional matching of circuit components by uniformly distributing circuit components in a manner that eliminates or significantly minimizes the sensitivity of such circuit components to environmental effects and process variations, thereby improving the performance of analog and mixed-signal circuits.
