Abstract: ADC accuracy is increased by 1 bit by interpolation of comparator outputs in a comparator array, thereby increasing accuracy without significantly increasing power consumption and size. Specifically, an analog-to-digital converter includes a binary converter and a comparator array, which comprises a plurality of comparator blocks, each block having a primary comparator and an interpolating comparator. The interpolating comparator compares an output signal from the primary comparator with a negative output signal from a primary comparator of another block of the plurality of blocks to generate a least significant bit. The binary converter, which is coupled to the array, converts array output to binary code.

Abstract: ADC accuracy is increased by 1 bit by interpolation of comparator outputs in a comparator array, thereby increasing accuracy without significantly increasing power consumption and size. Specifically, an analog-to-digital converter includes a binary converter and a comparator array, which comprises a plurality of comparator blocks, each block having a primary comparator and an intepolating comparator. The intepolating comparator compares an output signal from the primary comparator with a negative output signal from a primary comparator of another block of the plurality of blocks to generate a least significant bit. The binary converter, which is coupled to the array, converts array output to binary code.
