SYSTEM AND METHOD TO ENHANCE NOISE PERFORMANCE IN A DELTA SIGMA CONVERTER
Last updated:
Abstract:
Systems and methods for improving noise efficiency in a Delta Sigma modulator. A bypass scheme for a noise splitter is disclosed that reduces toggling activity for small signals. In particular, a sample-by-sample bypass noise splitter is disclosed that includes a noise splitting module and a bypass line. The bypass line bypasses the noise splitting module when signals are below a selected threshold, increasing efficiency of the system.
