Abstract
Methods and devices for an improved delta sigma modulator. The delta sigma modulator has multiple filters with at least one high order filter processing the MSBs of the quantizer fractional output and at least one lower order filter processing the LSBs of the quantizer fractional output. The outputs of these filters are then combined with the input through a combiner with the result being received by the quantizer. The quantizer then produces the output integer bitstream along with the fractional bitstream.
