Digital Error-Averaging Technique for Pipelined Analog-to-Digital Converter
, 2007 比較型類比數位轉換器是目前速度最快的一種，然而在提高解析度的需求時，則需要增加大量的比較器，同時轉換器的消耗必v、晶片面積也因而增加。因此，導管型類比數位轉換器是目前比比較型類比數位轉換器更適合發展快速及高解析度的架構。但是，導管型架構的類比數位轉換器其準確度很容易受到內部電路特性的影響，精確度受限的因素有運算放大器與比較器的非理想補償電壓、運算放大器的直流開迴路電壓增益、運算放大器的非線性程度、製程中電容不匹配的發生等等，其中造成轉換器非線性誤差的原因以電容不匹配的影響較為主要。到目前為止 ...
