Advanced Techniques for ADCs for 5G Receivers Abstract: In 5G systems, ADCs play a key role to increase the capacity and flexibility of the network. Depending on the system architecture, different scenarios result in different requirements for the ADCs. In handheld devices, focus is on low power design solutions and high bandwidths with moderate accuracy. In baseband stations, recent advances in technology and design techniques enable low-power Giga-sampled ADCs supporting direct-RF architectures. For massive MIMO systems, low-power, low-area solutions are needed to realize digital-intensive architectures. To accommodate for different use cases, flexible ADCs with e.g. a variable resolution are preferred. Design cases of ADCs suitable for high-performant 5G systems will be discussed.

Bio:
Ewout Martens (M’08) was born in Genk, Belgium,in 1978. He received the M.Sc. degree in 2001 and Ph.D. degree (summa cum laude) in 2007 from the Katholieke Universiteit Leuven, Belgium. From 2001 to 2007, he was a Research Assistant with ESAT-MICAS Laboratories of the Katholieke Universiteit Leuven. His Ph.D. research was on model-ing of Delta-Sigma modulators and RF front-ends.He joined imec (SSET), Belgium, in 2010 as a Design Engineer for WLAN transceivers. His interests and work are related to the development of innovative
architectures for RF receiver front-ends, transceiver building blocks like PLL, filters and LNA, and ADCs for various applications including image sensors and wireless receivers.
