Patent ID: 7714607

Claim:
A resistor circuit comprising: n-stage (n is a positive integer equal to or larger than two) unit circuits, each of the n-stage unit circuits including: a first resistor element provided between a first terminal and a second terminal; a first disconnection element provided between the second terminal and a third terminal; and a second disconnection element and a second resistor element provided in series between the second terminal and a fourth terminal; the first terminal of each of the n-stage unit circuits being connected with a first interconnect; the fourth terminal of each of the n-stage unit circuits being connected with a second interconnect; the third terminal of a first-stage unit circuit of the n-stage unit circuits being connected with a third interconnect; and the third terminal of an mth-stage (m is a positive integer satisfying 2≦m≦n) unit circuit of the n-stage unit circuits being connected with the second terminal of an (m−1)th-stage unit circuit of the n-stage unit circuits.
