Abstract
Official abstract text for this publication.
A digital to analog converter (DAC) includes a thermometer coder that generates a plurality of micro-current source analog controls on a frame-by-frame or symbol-by-symbol basis and to process digital inputs from symbols or frames of data based on a thermometer coding to generate a plurality of micro-current source inputs. A plurality of micro-current sources generate a corresponding plurality of micro-current source outputs in response to the plurality of micro-current source inputs, wherein first selected ones of the plurality of micro-current sources are powered-off in response to the plurality of micro-current source analog controls for a first symbol or frame of the plurality of symbols or frames of data. A summing circuit generates an analog output based a sum of the corresponding plurality of micro-current source outputs.
First claim
Opening claim text (preview).
What is claimed is: 1. A digital to analog converter (DAC) for use in a transmitter for transmitting a plurality of frames of data, the DAC comprising: a thermometer coder configured to generate a plurality of micro-current source analog controls on a frame-by-frame basis and to process digital inputs from the plurality of frames of data based on a thermometer coding to generate a plurality of micro-current source inputs; a plurality of micro-current sources, coupled to the ther…
