Exploring the low-frequency performance of thermal converters using circuit models and a digitally synthesized source

Abstract

Abstract—Low-frequency errors of thermal voltage converters are described and estimated using a circuit model that includes easily measured parameters. A digitally synthesized source is used to confirm the estimated ac-dc differences in the 0.01 Hz to 40 Hz range. for than that produced by an equivalent voltage at a higher frequency where the temperature tracking is negligible. This tracking is the source of the low frequency errors that will be addressed in this paper. I.
