An analog-to-digital converter (ADC) having integrator dither injection
and quantizer output compensation reduces the probability of unchanging
code sequences that occur when the input signal and feedback signal are
equal and thus no quantizer output change occurs. In particular, in
modulators that are periodically reset, the dither reduces the
probability of a stuck code sequence at startup. The effect of the dither
is removed from the output of the ADC, either by subtracting an offset
value from the result of filtering the quantizer output, or directly from
the quantizer output itself.
