<P>PROBLEM TO BE SOLVED: To provide a feedback control circuit capable of suppressing signal transmission delay while reducing a circuit scale, a cost and power consumption, and a feedback control system including it in a part. <P>SOLUTION: The feedback control circuit includes: amplification means 12 for amplifying input signals; integration means 30 in one or more stages for performing an integration operation to output signals of the amplification means; one or more feed-forward routes FF1 for bypassing at least a part of the integration means and transmitting signals; addition means 22 for adding signals inputted from the integration means and signals inputted through the feed-forward route; quantization means 32 for quantizing the output of the addition means and generating output signals; and a feedback route FB1 for transmitting the output signals generated by the quantization means to the input side of the integration means of the final stage among the integration means in one, two or more stages. <P>COPYRIGHT: (C)2012,JPO&INPIT |
