Abstract
Apparatus and methods are taught for dividing a signal to be processed by a Noise Shaping (Hereafter NS) loop into smaller sections, and applying NS to at least a subset of these smaller sections. The processed signals are then recombined. As noise shaping is performed on smaller sections, the operating speed of each noise shaping loop, and accordingly for the system in general, is faster than if the output signal had been generated by single higher bit NS loop. Embodiments further include a configuration block for configuring the apparatus. For example, the number of sections, the section calculation method, and the NS for each section can each be configurable, and for some embodiments, programmable.
