Digitally self-calibrating current-mode D/A converter |
摘要 |
Digital self-calibration of digital-to-digital converters includes an approach to correct for the arbitrary errors in the analog section provided that there are sufficient redundancy in the architecture. The calibration procedure is performed off-line (upon power-up or user request). The digital correction technique avoids the need of a very accurate current mirror or an extra digital-to-analog converter as a standard transfer device.
