Abstract: In an analog to-digital converter, an analog signal is applied to a signal node of a binary weighted capacitor array during a sampling interval to charge capacitors of the capacitor array. A reference voltage is selectively applied to individual capacitors of the capacitor array during a coding interval to redistribute charge among the capacitors and to thereby minimize a voltage at the signal node. A compensating signal responsive to transitions of an error producing signal is coupled to the signal node during the sampling and coding intervals. The bit pattern corresponding to the sample of the analog signal is determined from which capacitors of the array have the reference voltage applied thereto for minimizing the voltage at the signal node. The analog-to-digital converter is useful for codecs used in telephony applications for encoding and decoding voice signals and the like.
