ABSTRACT:
For mixed signal and RF integrated circuits, the problem of substrate coupled noise can be resolved by using a moat (12) formed in the common substrate to substantially surround sensitive circuits (16). Signal bridges (18, 19) may be formed to provide a path for signals to and from the sensitive circuits (16).
