Abstract
An ADC having a sparkle suppression capability equivalent to that of a full bit Gray encoding method and preventing criss-crossing of interconnections nor an increase of the pipeline delay, wherein a resistor string for generating reference voltages to be compared with an analog input signal is folded 2 times or a multiple thereof corresponding to the number n of most significant bits of the output bit ADB of the related ADC. It has a first encoder for encoding the most significant n bits and outputting a Gray code, second encoders for encoding least significant bits and outputting the same, a first output circuit for converting the Gray code output from the first encoder to a binary code and generating most significant n bits, and a second output circuit for generating least significant bits by using the digital code generated by the first output circuit and the output of the second encoder.
