A switchable capacitance circuit according to one embodiment of the present invention includes a plurality of capacitance-switch cells which include a first semiconductor switching circuit and a capacitance circuit with a first terminal which is connected to the first semiconductor switching circuit, respectively. The resistance of the first semiconductor switching circuit of a first capacitance-switch cell of the capacitance-switch cells is within a first allowance error of the resistance of the first semiconductor switching circuit of a second capacitance-switch cell of the capacitance-switch cells. The capacitance of the capacitance circuit of the first capacitance-switch cell is within a second allowance error of the capacitance of the capacitance circuit of the second capacitance-switch cell. |
