Techniques for delay compensation of continuous-time sigma-delta modulators

Image Number 2 for United States Patent #7834787.

A technique for implementing compensatory feedback in a continuous-time sigma-delta modulator includes providing, based on an analog input signal, a digital output signal at an output of a quantizer circuit of the continuous-time sigma-delta modulator. A functionality of the quantizer circuit is then controlled based on the digital output signal.
