Process-Independent Resistor Temperature-Coefficients using Series/Parallel and Parallel/Series Composite Resistors

—this paper introduces series/parallel and parallel/series composite resistor topologies. These topologies allow one to design a temperature coefficient that is insensitive to process variations, unlike the traditional simple series and simple parallel composite resistors. Formulas and normalized circuits are provided. Four zero-temperature coefficient resistors are simulated, and methods for picking the best topology are discussed.
