High performance, low complexity 0.18 μm SiGe BiCMOS technology for wireless circuit applications

Abstract

High frequency performance at low current density and low wafer cost is essential for low power wireless BiCMOS technologies. We have developed a low-complexity, ASIC-compatible, 0.18 /spl mu/m SiGe BiCMOS technology for wireless applications that offers 3 different breakdown voltage NPNs; with the high performance device achieving F/sub t//F/sub max/ of 60/85 GHz with a 3.0 V BV/sub CEO/. In addition, a full suite of high performance passive devices complement the state-of-the-art SiGe wireless HBTs.
