Abstract

The aim of this review paper is to define the role of SiGe HBTs within the Technology Revolution that will lead to a globally interconnected smart world. At first, the authors have presented the recent developments of SiGe BiCMOS technologies and their applications to unit circuit blocks and integrated solutions. Then modern HBT device structures, technological aspects, scaling strategies, design issues, and future directions are also discussed. TCAD-based simulations predict that SiGe HBTs with cut-off and maximum oscillation frequencies of 780 GHz and 2 THz, respectively will become feasible by the year 2030.
