Abstract
An A/D converter includes at least one comparator array (COMP–COMP) for flash A/D conversion of an analog signal. Means (CCU, SW–SW) provide, for each comparator in the array, a common reference signal to both comparator input terminals. Means (CCU, DAC–DAC) force each compara-tor in the array into the same logical output state. Finally, means (CCU, DAC–DAC) adjust the comparator trip-point for each comparator by a ramp signal until the logical output state is inverted.
