Abstract
A modified pipeline architecture allows the simple implementation of a foreground calibration technique with the continuous calibration benefits of the background calibration techniques. To calibrate a stage in the pipeline, a calibration voltage is presented to the input instead of the output from the previous stage. To prevent loss of information, the output data of the previous stage is passed on to a stage further down.
