Abstract
A method includes using a first feedback loop to compensate for a first excess loop delay (ELD) associated with a first quantizer and a first DAC of the first feedback loop. The first quantizer provides a first quantizer output to a second feedback loop. A second feedback loop compensates for a second ELD associated a second quantizer and a second DAC of the second feedback loop. The second quantizer reduces a metastability error associated with the first quantizer output.
