Abstract
A method and apparatus for a feed-forward delta-sigma modulator are provided. The apparatus includes a first adder configured to receive a feedback signal and an input signal and a first integrator configured to receive an output from the first adder. The apparatus also includes a noise-coupled summer/integrator (NCSI). The NCSI includes a second adder configured to receive a differentiation path from the first integrator, an output from the first integrator, and a delayed feedback path from the output of a second integrator. The NCSI also includes the second integrator configured to receive an output from the second adder. The apparatus also includes a quantizer configured to receive the output of the second integrator, feed back the output to the first adder and the NCSI and produce the output from the feed-forward delta-sigma modulator.
