Abstract
Methods and apparatuses embodied in delta sigma domain digital signal processing circuits that perform linear operation of delta sigma modulated bit stream, including adding, coefficient multiplication, and compressing. The digital processing circuits perform on-the-fly processing to generate a continuous output delta sigma bit-stream based on the continuous input delta-sigma modulated bit-streams and the input binary coefficients. The on-the-fly bit-stream processing circuit is realized via digital delta sigma modulators with input coefficient multiplexers, feedback multiplexers, and toggling multiplexers.
