A simple model for the prediction of AC-DC difference of multi-junction thermal converters

This paper describes a simple model for planar multi-junction thermal converters based on physical dimensions and properties of the converter chip and all wire bonds. The model was used to explain extremely low (<; 700 μV/V) AC-DC differences at 100 MHz. Two designs of multi-junction thermal converters (MJTC) were tested against the model and the results are presented.
