- SiGe BiCMOS integrated circuits for high-speed serial communication links
- Considerable progress has been made in integrating multi-Gb/s functions into silicon chips for data-and telecommunication applications. This paper reviews the key requirements for implementing such functions in monolithic form and describes their implementation in the IBM SiGe BiCMOS technology. Aspects focused on are the integration of 10-13-Gb/s serializer/deserializer chips with...
