Pesenti, S.Clement, P.Stefanovic, D.Kayal, M.2010-10-212010-10-212010-10-21200710.1109/MIXDES.2007.4286151https://infoscience.epfl.ch/handle/20.500.14299/55946This paper presents a hybrid continuous-discrete-time Delta-Sigma modulator for portable communication systems following a low-power strategy. The proposed design methodology is extendable to different specifications. A multi-bit technique has been introduced in an efficient manner to optimize the power consumption, and an adaptive algorithm is used to allow for a 3-fold reduction in the number of comparators.
