SYSTEM AND METHOD FOR TRI-LEVEL LOGIC DATA SHUFFLING FOR OVERSAMPLING DATA CONVERSION

摘要

A system is disclosed for processing digital signals in a data converter. The system includes a thermometer encoder (12) for receiving signed binary data and for providing signed thermometer data. The signed thermometer data includes positive thermometer data and negative thermometer data. The system also includes a shuffler (18) that receives positive input data responsive to the positive thermometer data and receives negative input data responsive to the negative thermometer data. The system also includes a decoder (20) for receiving output data from the shuffler and providing decoded data to an analog output stage.
