INTEGRATED POLY-PHASE FIR FILTER IN DOUBLE-SAMPLED ANALOG TO DIGITAL CONVERTERS |
摘要 |
A sigma delta analog to digital converter includes a clock operating at a conversion clock rate and first and second conversion paths. The first path includes a first sigma delta modulator configured to produce from an input analog signal a first bit stream at the clock rate, and a first digital filter configured to decimate the first bit stream. The second conversion path has a second sigma delta modulator configured to produce from the input analog signal a second bit stream separate from the first bit stream at the clock rate, and a second digital filter configured to decimate the second bit stream.
