| 1. A semiconductor integrated circuit comprising:
a first circuit where N sets of a switch and a capacitor connected in series are inserted in parallel between a power source
voltage line and a ground line;
a second circuit where N sets of a switch and a capacitor connected in series are inserted in parallel between a signal line
and the ground line or the power source voltage line; and
a 2N-bit register which arbitrarily turns ON or OFF said N switches in the first circuit and said N switches in the second
circuit.
