Abstract
The disclosed conversion device converts an analog input signal into a digital signal and outputs thereof, wherein the conversion device comprises a feedback signal generator for performing mismatch shaping on the digital signal that has been converted and output, and then performing digital-analog conversion to generate a feedback signal; a subtractor for subtracting the feedback signal from the analog input signal and outputting thereof; a serial-parallel converter for converting the signal output from the subtractor into a plurality of parallel signals and outputting thereof; a vector filter for performing signal processing on the plurality of parallel signals output by the serial-parallel converter and outputting a plurality of signals; a quantizer for quantizing the plurality of signals output by the vector filter and outputting digital signals; and a parallel-serial converter for converting the digital signals output by the quantizer into serial signals and outputting thereof.
