A fully automated approach for analog circuit reuse

Demonstrated in this paper is a technique for automatic circuit resizing between different technologies. This technology is not based on any optimization techniques, but rather relies on a new algorithm based on knowledge extraction, which makes it a very fast technique. This technique studies the original design and extracts its major features (basic devices & blocks features, device matching, parasitics, and symmetry) and then reproduces a new sized design in the target technology with the same performance as the original design. The migration of a low voltage delta sigma A/D is presented in this paper to validate the migration engine.
