PROBLEM TO BE SOLVED: To provide a highly flexible compensation method for common mode voltage.SOLUTION: Each of a plurality of input capacitances (Cs1p, Cs2p, ...) on the positive side receives in parallel a plurality of input signals on the positive side in a plurality of differential input signals. An adjustment capacity Cxp on the positive side receives voltages on the positive side for adjusting the common mode voltage. Each output terminal of the input capacitances (Cs1p, Cs2p, ...) on the positive side and an output terminal of the adjustment capacity Cxp on the positive side are combined into one. Each of a plurality of input capacitances (Cs1m, Cs2m, ...) on the negative side receives in parallel a plurality of input signals on the negative side in the plurality of differential input signals. An adjustment capacity Cxm ont the negative side receives voltages on the negative side for adjusting the common mode voltage. Each output terminal of the input capacitances (Cs1m, Cs2m, ...) on the negative side and an output terminal of the adjustment capacity Cxm on the negative side are combined into one. |
