摘要：
A filter circuit according to the present invention includes a voltage-current conversion unit that converts a voltage signal input to an input end to a current signal, a capacitor group that is made up of a plurality of capacitors, where the current signal output from the voltage-current conversion unit is sequentially input to each capacitor at every cycle, a first switch that connects a set of capacitors to which the current signal is input with each other and adds charges accumulated in the set of capacitors together, and a second switch that connects at least one capacitor of the set of capacitors to an output end after charges are added by the first switch.
