In this paper the theoretical operation of incremental (charge-balancing) delta-sigma (∆Σ) converters is reviewed, and the implementation of a 22-bit incremental A/D converter is described. Two different analyses of the first-order incremental converter are presented, and based on these results two extensions to higher-order modulators are proposed. Since line-frequency noise suppression is often important in measurement applications, modulators followed by sinc k filters are also analyzed.doi:10.1109/cicc.2006.320960 dblp:conf/cicc/MarkusDQST06 fatcat:k3fhqg74dzdyjjdypuvhbwzy5y
