ABSTRACT:
For certain high-speed applications, where high-precision is not required analog-to-digital conversion may be performed by employing several comparators, each having their own offset. Each such comparator with an offset may be constructed by employing a differential amplifier with an offset followed by a conventional comparator. Advantageously, the time to obtain a conversion to digital of an analog sample is reduced in comparison to prior art converters, thus enabling high-speed operation.
