A novel approach for high-frequency pipelined A/D conversion

Flash and parallel approaches are compared with the pipeline solution, and the advantages of the latter technique are evaluated. A pipeline design is examined extensively, and circuit improvements suitable for increasing conversion speed are described. The proposed scheme includes a self-calibration to compensate conversion errors, in particular the error resulting from the use of very fast op-amps with low DC gain. A novel approach for speeding up the pipeline converter, referred to as digital assisted slewing is proposed.<>
