The two-dimensional temperature profile of a multi-finger power SiGe HBT is studied with the electrothermal model, which shows that there is an uneven temperature profile over the device finger for HBT with uniform finger length. Because of the positive current-temperature feedback, the uneven temperature profile will leads to an anomalous current distribution, which eventually caused the thermal...
As an effective and feasible method, the technology of non-uniform emitter finger spacing has been used to alleviate the thermal effects and improve the uneven temperature profile in multi-finger power SiGe HBTs. However, for the HBT with dozens of emitter fingers, designing multiple finger spacing values becomes trivial and time-consuming. In the paper, a new thermal design methodology namely Grouping...
