Mr. Khaled Khalaf

Biography

Khaled Khalaf received the B.Sc. degree in electrical engineering from Ain Shams University, Cairo, Egypt, in 2005, and the M.Sc. degree in electrical engineering from Delft University of Technology, Delft, The Netherlands, in 2010. In 2005, he was employed by Scenario Design Services, Cairo, Egypt, and spent 2 years at Infineon Technologies AG., Munich, Germany. Currently he's pursuing the Ph.D. degree in electrical engineering from Vrije Universiteit Brussel, and doing his research at Imec, Leuven, Belgium, on low-power CMOS transmitter ICs for 60 GHz applications. Through his research, he was involved in the design and implementation of several RF/mm-wave blocks for wireless applications.

Research Interest

Recently around 7 GHz of unlicensed frequency band around 60 GHz has been allocated for high data-rate wireless communication. This allows for wireless data transfer with the rate of tens of gigabits per second. The main objective of this research is to explore low-power techniques for the implementation of the 60 GHz transceiver chip. This is required to increase the battery life time in mobile applications. Phased arrays can be used to overcome signal losses at 60 GHz. Advanced digital CMOS technology is adopted in this project to provide a low-cost single-chip CMOS transceiver solution with analog and digital functionalities for consumer applications. Recently 7 GHz of unlicensed frequency band around 60 GHz has been allocated for high data-rate wireless communication. This enables the usage of various applications including wireless streaming of high definition video signals in few seconds and short range broadband internet access. This research aims at exploring low-power mm-wave CMOS transmitter chips.
