High-Speed Analog-to-Digital Converters in SiGe Technologies

SiGe-based high-speed ADCs are promising for emerging higher frequency band applications such as coherent optical systems or millimeter-wave radios because of the inherent advantages of high-speed, high integration, and high yield technology. This paper addresses recent developments in high-speed ADCs in SiGe technology. An approach is then presented for development of ultra-high-speed ADCs for the next-generation wired or wireless communication systems.
