ABSTRACT:
Link capacitors are used to establish connection between joining-points of coupling capacitors and inverters in an inverter chopper comparator array, in order to reduce injected electric charge variation due to feedthrough. Some of the comparators in the comparator array, arranged at each end thereof, constitute a redundant comparator array without connection to a logic circuit that is used to obtain an A/D conversion output. This reduces the effects of the device parameter variations in the comparator array whereby a high accuracy voltage comparison is achieved, and noise-resistant strength is improved.
