My research focus is on synchronization architectures for milli-meter wave receivers for multi-gigabit data transmission. Receiver synchronization is a complete analog block with low power consumption which allows us to design a true wireless receiver reaching an ambitious 100 Gbps data speeds. I am presently focusing on Costas Loop architectures both for BPSK and QPSK data modulation schemes.

Areas of expertise:

High frequency circuit design, SiGe Technology, receiver synchronization schemes for mmW systems, RF PCB design and packaging.
