Abstract
A semiconductor integrated circuit includes: a first capacitance element and a second capacitance element; a first amplification circuit that amplifies a potential difference of a first voltage signal and a second voltage signal supplied via the first capacitance element and the second capacitance element, respectively, to output a first amplification signal and a second amplification signal; a first resistance element that feeds back the first amplification signal to one input terminal of the first amplification circuit; a second resistance element that feeds back the second amplification signal to another input terminal of the first amplification circuit; a voltage generator that generates a predetermined voltage; and a third resistance element that transmits the predetermined voltage generated by the voltage generator to each input terminal of the first amplification circuit.
