He is pursing PhD from CeNSE, IISc Bangalore, under the guidance of Prof Shankar Kumar Selvaraja since Aug 2016. His research focus is on understanding the electro-magnetic and electro-optic interactions and design CMOS/BiCMOS transceiver circuity for RF over fiber communication link using silicon photonics technology. He has received his B.Tech (Hons) from National Institute of Technology, Rourkela in 2009. He was Summer Research Fellow of IASc-INSA-NASI in 2008. He received DRDO Technology Group Award (Lab level):2016 for S-band CMOS transceiver design. He is a member of IEEE, Life fellow of optical society of India (OSI), Life member of Indian Science congress association (ISCA) and life member of Indian Society of Remote Sensing (ISRS).
The performance characteristics of a typical beam forming radar is determined by number of elements that can be integrated in an array and effective routing of RF signal and hence optimizing the overall of Size, Weight, area, Power and cost (SWAP-C). RF over the fibre communication using Silicon-photonics is one of the most attractive solutions to overcome this trade-off owing to their significantly lower loss, lower weight and enhanced immunity to electromagnetic interference. Apart from this, accuracy of the system can be enhanced by better components circuitry design for beam forming elements. In this work, we have adopted IF-beam forming architecture and proposed the optimization of silicon-photonics assisted beam forming radar by design and development of highly accurate 7-bit CMOS phase shifter, high precision phase compensated 8-bit CMOS attenuator, miniaturized differential SPDT switch and broadband transimpedance amplifier.
