Abstract
A sliding scale averaging technique is employed for an analog-to-digital converter. An analog signal is summed with a varying number prior to conversion. This causes repeated input voltage signals of the same value to be converted in different bins of the ADC converter thereby minimizing errors due to unequal bin widths. The present invention includes a comparator technique for ensuring that the summed signal does not exceed the full dynamic range of the ADC.
