ABSTRACT:
The ΔΣ AD converter includes: a sampling section for sampling an input signal at each cycle Ts; an AD conversion section for performing AD conversion of the input signal; a DA conversion section for performing DA conversion of an output of the AD conversion section; and a loop filter for integrating a difference obtained by subtracting an output of the DA conversion section from an output of the sampling section so as to output the integrated difference to the AD conversion section, wherein the sampling section includes two sampling circuits disposed parallel to each other, and the two sampling circuits respectively operate at timings different from each other, and each of the sampling circuits delays the input signal so as to output the delayed input signal.
