Abstract
We investigate the impact of the non-ideal temperature dependence of IC-VBE on the performance of ultra-wide temperature range SiGe HBT bandgap reference circuits. Both the slope and intercept of IC-VBE show temperature dependences that significantly differ from “ideal” Shockley theory widely used in BGR analysis and design, and are shown to have significant impact on ΔVBE(T), IC (T) and VBE(T).
