| 20100007322 | RESISTOR UNIT AND A CIRCUIT INCLUDING THE RESISTOR UNIT - A resistor unit is adapted for use in a constant current source circuit or a temperature compensating circuit for providing temperature compensation to a constant voltage reference circuit. The resistor unit includes at least one first resistor, and at least one second resistor coupled to the first resistor. One of the first and second resistors is a positive temperature coefficient resistor. The other one of the first and second resistors is a negative temperature coefficient resistor. Because a temperature characteristic of the first resistor is opposite to that of the second resistor, an effective resistance of the resistor unit changes in a relatively narrower range with temperature. | 01-14-2010 |
