Abstract

This 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.
