Development and characterization of a new low-loss monolithic AC switch based on super-gain BJT

This article deals with the development of an innovative low-loss monolithic AC switch based on super-gain BJT manufactured on silicon substrate. The GREMAN laboratory has started this study for ten years. Two main categories of AC switch are described: hybrid AC switch (based on the discrete association of 2 super-gain BJTs) and monolithic AC switch. The key criteria to design and process the monolithic power device are particularly discussed taking into consideration its application areas and its manufacturability.
