Transceiver Design for Cellular: Challenges and Directions

Speaker: Krishnaswamy T.

Abstract

The talk will cover on the key design challenges facing Transceiver design for Cellular Standards (2G-5G NR). Starting with a short recap of the Cellular Spectrum and Standards and the unique design challenges it imposes on the Transceiver. Finally we delve into some key blocks and problem statements that the audience can mull over for future research.

Bio

Passed out of IIT KGP in 2003 with a President’s Silver Medal. Worked with Texas Instruments from 2003-14. While at TI worked on transceivers in sub-micron CMOS processes for GPS, BT and WLAN and on fast switching Fractional-N RF PLL’s for PMR Systems . Led the development of a 30dBm Integrated WiFi PA on 45nm CMOS while at TI. From 2014’ to present day working at Qualcomm on designing Multi-Mode, Multi-Band Transceivers primarily for Celullar Standards (2G-5G) as well as IoT radios. Research Interests include digitally assisted RF chains and fast settling low spurious emission RF PLL’s. Presently leading a team of 35 RFIC design engineers working on Cellular/IoT radios and discrete RFIC to achieve sub-1dB Noise Figure for Sub-6GHz Cellular bands. Holds 19 patents and 3 IEEE publications (2 at ISSCC and 1 ISCAS).
