SYSTEM AND METHOD TO ENHANCE NOISE PERFORMANCE IN A DELTA SIGMA CONVERTER

Last updated:

Abstract:

Systems and methods for a power-efficient 3-level digital-to-analog converter. A converter cell using a current starving technique keeps a portion of the converter cell turned on in a low power mode, as opposed to completely turning off current in selected modes. A conversion system keeps a first set of converters active while allowing a second set of converters to be powered down. Systems and methods presented save power and allow for efficient reactivation of converters.
