Abstract
Exemplary sigma-delta modulators include a summing block configured to receive an input signal, a noise shaping unit configured to process an output signal of the summing block, a quantizer configured to quantize an output signal of the noise shaping unit, and a current-mode digital-to-analog converter (“DAC”) configured to convert an output of the quantizer into an analog signal and input the analog signal into the summing block in a closed loop feedback manner.
