Systems and methods are described for improving the accuracy of A/D converters. The method includes sampling an input voltage and a reference voltage substantially simultaneously, transmitting both the sampled input voltage and the sampled reference voltage to an analog-to-digital converter, and producing a digital signal based on the sampled reference voltage and the sampled input voltage. The apparatus includes first and second samplers coupled to receive a reference voltage and an input voltage and operating to sample the voltages substantially simultaneously, and an A/D converter, which receives input from the first and second samplers.
