Analysis on Capacitor Mismatch and Parasitic Capacitors Effect of Improved Segmented-Capacitor Array in SAR ADC

Authors: Sun Lei, Dai Qinyuan, Qiao Gaoshuai and Lee Chuangchuan

2009 Third International Symposium on Intelligent Information Technology Application

Abstract—This paper presents an analysis on capacitor mismatch and parasitic capacitors effect of the improved segmented-capacitor array to alleviate the limitation of mismatching performance and avoid a non-binary-weighted coupling capacitor. Both the matching of binary-weighted capacitor network and parasitic capacitors on both sides of the coupling capacitor have great influence on the resolution of ADC system. The relationship among the mismatching of binary-weighted-capacitor network and the parasitic capacitors and the attainable resolution of ADC is analyzed by giving precise theoretical demonstration. Therefore, a theoretical basis is provided for designers to choose process, layout, circuit structure, and capacitor size in their design of SAR ADC
