Abstract:
A circuit includes first and second capacitances arranged on a first path that connects first and second terminals; a first switch arranged between the first capacitance and the second capacitance; a second switch arranged on a second path that connects a reference voltage section and a first node formed between the first capacitance and the first switch; a third switch arranged on a third path that connects the section and a second node formed between the second capacitance and the first switch; a first resistance arranged on a fourth path that connects the first node and a third node formed between the first terminal and the first capacitance; a second resistance arranged on a fifth path that connects the second node and a fourth node formed between the second terminal and the second capacitance; a fourth switch on the fourth path; and a fifth switch on the fifth path.
