ELEN3331 Electronic Circuits,ELEN6904 xG Transceiver Architectures

Research on on-chip cryogenic CMOS (4 K) VCO phase noise constraints for qubit readout and control in quantum computing.

As a Senior Engineer at Samsung Semiconductors, I designed, tested, and evaluated Integrated Circuits - GPIOs, oscillators, and other analog blocks. I also led the oscillator design, taking ownership of architecture design and testchip functionality.I have worked on various technology nodes, including 3 nm and 14 nm - 3D FETs and planar MOS.

As a Research Assistant guided by Professor Dr.P.V.Ramakrishna, I worked on RF communication systems including GPS and FMCW Radars, and cubesat ANUSAT II verification. Key Achievements: 1) Developed FMCW (Frequency Modulated Continuous Wave) Radar RF receiver chain in C-Band and examined -40 dB Tx-Rx direct leakage in wireless transmission2) Determined RCS of target objects and SNR threshold for false alarm reduction; improved receiver SNR by 10 dB in mmWave Radar by integrating frames3) Implemented the GPS receiver chain as a team, including FLL (Frequency Locked Loop), DLL(Delay Locked Loop), Costas Loop for Doppler and code frequency correction, and achieved a receiver sensitivity of -127 dBm4) Devised CDMA-based transceiver for high-precision altitude tracking in spread spectrum Altimeter with low sensitivity of -127 dBm and demonstrated it to the Defence Research and Development Organisation (DRDO) for implementation
