Abstract:
A digital delta sigma modulator includes an input integration stage, a resonating stage, a quantizer, and a plurality of feedback paths operably coupled to the quantizer, the input integration stage, and the resonating stage. The input integration stage is operably coupled to integrate a digital input signal to produce an integrated digital signal, wherein the input integration stage has a pole at substantially zero Hertz. The resonating stage is operably coupled to resonate the integrated digital signal to produce a resonating digital signal, wherein the resonating stage has poles at a frequency above zero Hertz. The quantizer stage is operably coupled to produce a quantized signal from the resonating digital signal.
