Expandible high-order cascade ya modulator with constant, reduced systematic loss of resolution
(Institute of Electrical and Electronics Engineers, 2003)
An arbitrary order sigma-delta modulator cascude architecture is presented with only I-bit loss of resolution due to scaling issues, even with single-bit quantizulion. This loss is kept with a high overloading point, ...
