Claim Text:
1. An integrated resistor comprising: a semiconductor substrate having a top surface; and a resistor formed over the top surface of the semiconductor substrate from one or more portions of one or more layers of resistive material, wherein the resistor includes an input end, an output end, a first resistive section having a first length defined between a first end of the first resistive section and a second end of the first resistive section, wherein the first end of the first resistive section corresponds to the input end of the resistor, and the first end of the first resistive section has a first width, and wherein the second end of the first resistive section has a second width in a range of 5 percent to 60 percent of the first width, and a second resistive section coupled in series with the first resistive section, wherein the second resistive section has a second length defined between a first end of the second resistive section and a second end of the second resistive section, wherein the first end of the second resistive section is coupled to the second end of the first resistive section, wherein the second resistive section has a third width at the first end of the second resistive section, and a fourth width at the second end of the second resistive section, wherein the fourth width is at least 5 percent greater than the third width, and wherein the second end of the second resistive section corresponds to the output end of the resistor.
