Our paper titled "Third Quadrant Operation of SiC MOSFETs: Comprehensive Analysis and Condition Monitoring Solution" has been published in the IEEE Transactions on Components, Packaging and Manufacturing Technology. By investigating the intricate relationship between gate voltage bias, gate oxide degradation, and third quadrant operation, our study offers valuable insights to enhance SiC MOSFET performance and reliability.

Sharing a recent article published by my group in "The IEEE Transactions on Antennas and Propagation" which is a prestigious peer-reviewed journal in our research field.  We focuses on the design and development of a Frequency Selective Surface (FSS) that is specifically engineered for electromagnetic interference (EMI) shielding in the n257 band (26.5–29.5 GHz) of 5G communications. The reformed geometry of the proposed FSS provides a high selective stopband filtering response while maintaining high performance in terms of shielding effectiveness, polarization insensitivity, and angular stability. The design leverages innovative geometries to maximize performance in a compact and conformal form factor. https://lnkd.in/grNhDZdY

Focus Microwave’s development of a new Keysight PNA-x-based noise parameters extraction system tailored for on-wafer applications at D-Band marks a significant advancement in millimeter-wave testing capabilities. This cutting-edge solution focuses on enabling precise on-wafer measurements of active circuits operating at millimeter-wave frequencies, particularly in the challenging D-Band spectrum. This innovation holds the promise of enhancing precision and success in noise figure measurements for active circuits in millimeter-wave applications as proven in the joint scientific paper with Keysight : N.

This paper present #JUMP, the first system enabling practical bistatic and asynchronous joint communication and sensing, while achieving accurate target tracking and micro-Doppler extraction in realistic conditions. Their system compensates for the timing offset by exploiting the channel correlation across subsequent packets. Further, it tracks multipath reflections and eliminates frequency offsets by observing the phase of a dynamically-selected static reference path. JUMP has been implemented on a 60 GHz experimental platform, performing extensive evaluations of human motion sensing, including non-line-of-sight scenarios. In their results, JUMP attains comparable tracking performance to a full-duplex monostatic system and similar micro-Doppler quality with respect to a phase-locked bistatic receiver. ---- Jacopo Pegoraro, Jesus O.

Exciting News! My Paper Published on IEEE! I am thrilled to announce that my latest conference paper that was presented at the 25th International Symposium on Quality Electronic Design (ISQED’24), titled as "HiCTL: High Fan-in Differential Capacitive-Threshold-Logic Gate Implementation With An Offset-Compensated Comparator"has been published on IEEE. This work introduces a novel threshold logic gate with high fan-in capability, low propagation delay, and compact area, making it ideal for applications requiring fast, data-intensive computations. Key highlights of the paper include: - A new threshold logic gate design using capacitive feedback for offset compensation. - Analytical and post-layout analysis demonstrating high fan-in implementation and performance metrics. This publication was made possible through the collaboration and support of my mentors Dr. Martin Margala and Dr. Ugur Cilingiroglu I am grateful for their guidance and insights. #Research #IEEE #Publication #LogicDesign #CMOS #ThresholdLogic #HighFanIn #CapacitiveFeedback #ElectronicDesign For those who are interested, please read the full paper here:

Our recent work in IEEE Electron Device Letters (EDL) studies the scaling limit of Ferroelectric thickness in CMOS-compatible FeFETs posed by the direct gate-tunneling current. The interplay between the domain's density and polarization gradient determines the scaling limit. Thanks to the co-authors, for sharing your valuable insights. Prof(s) Sanjay Banerjee, L.F.

I am pleased to share our new published article presented at 2024 22nd IEEE Interregional NEWCAS Conference (NEWCAS) entitled "Capacitively Isolated 400 Mbps Data Transfer System with 2 Ns Propagation Delay and 5 kV /µs Common Mode Transient Immunity". Thanks to all co-authors for their contribution. Abstract: This paper presents the implementation and measurements of an isolated capacitively coupled data transfer system capable of sustaining a 355 V rms breakdown voltage in a 3.3 V 0.18 µm CMOS process. The design is based on the pulse amplitude modulation scheme which consumes minimum silicon area and lower propagation delay. The receiver (Rx) demodulation circuit implements a pre-amplification stage to mitigate the common mode (CM) transient surge. Measurement results show that our fabricated chip prototype operates at a wide range of data rates between 1 kbps and 400 Mbps with a propagation delay of 2 ns. Moreover, the differential architecture achieves 5 kV/µs common mode transient immunity (CMTI). Our presented system shows a total energy consumption of 19.74 ×10^3 pJ/b at 1 Mbps.
