CircuitAvishkar2.0, the 2nd Edition of Industry grade hackathon came to action on the 27th and 28th February 2026 at the prestigious Reva University in Bangalore, organized by IEEE CASS Bangalore Chapter in close collaboration with the industry partner and financial sponsors Infineon Technologies India Pvt. Ltd. The event saw participation from 150+ students from various branches of B.Tech. and M.Tech, across 6 Indian states and 16 different universities. At the inception of CircuitAvishkar the organizing committee questioned the outcomes of hackathons: “Why do most hackathons end at the prize ceremony,” “Why not go beyond the traditional aptitude-based hiring,” “Why not the end goal be a career instead of a trophy.” The outset of those questions in 2024 was CircuitAvishkar - A one of a one of a kind hackathon which provides apprenticeship to students who perform well in the hackathon. The hackathon is designed to test practical and live technical skills over traditional theoretical understanding of concepts. It tests the aptitude and attitude of the candidate with a specific problem aligned to industry executions, and measurable & timebound outcomes defined. Students get to work on cutting edge technologies of Infineon Technologies India Pvt. Ltd, during the hackathon. The 2-day event started on 27th February 2026 with a lively Inauguration and ended on the 28th February with the announcement of the students selected for the further process of selection by Infineon Technologies India Pvt. Ltd. Under the unwavering mentorship of Dr. Rajiv Joshi (IEEE CAS Vice President of Industry), this event maintains a strong legacy of leadership, endorsed by industry experts and past CASS Chairs Mr. Ayan Datta of SanDisk and Dr. Devesh Dwivedi of GlobalFoundries with continued support from the IEEE Bangalore Section.

Belonging is a fundamental determinant of human wellbeing, shaping mental health, resilience and behaviour across the course of life. Yet contemporary digital systems increasingly prioritise engagement, visibility and individual optimisation over the conditions that sustain authentic belonging. Despite unprecedented connectivity, loneliness and social fragmentation continue to rise. Here, we propose a new paradigm: Quantified Others, a biologically informed framework for digital belonging grounded in shared biological traits rather than social performance or algorithmic similarity. Drawing on socio-genomics, network science and behavioural psychology, we argue that trait-level biological variation naturally gives rise to structured similarity between individuals at population scale. Using empirical observations from large-scale deployment of trait-based biological matching systems, we show that individuals cluster into overlapping affinity groups defined by shared biological experience. We suggest that these emergent biological similarity networks provide a natural substrate for empathy, identity formation and collective behaviour change. By embedding biological resonance into digital architectures, Quantified Others offers a pathway towards social systems that prioritise belonging, coherence and wellbeing over engagement metrics.
Wideband transmission in current Wi-Fi 7 (IEEE 802.11be-evolution) and 5 G cellular communication systems has enabled significantly higher throughput in the 6-GHz band (5.925–7.125 GHz) worldwide. However, the use of wider bandwidths introduces several critical challenges for both Wi-Fi and 5 G networks. One of the most important challenges is maintaining high energy efficiency under wideband operation. To achieve high energy efficiency, power amplifiers (PAs) should operate in or near saturation, where nonlinear distortion is introduced and degrades transmitter performance. In this article, dynamic compensation techniques based on digital and RF predistortion are investigated to mitigate power-amplifier (PA) nonlinearity in broadband wireless transmitters. The work addresses key challenges in Wi-Fi 7 and 5G systems, including wide transmission bandwidths, high peak-to-average power ratios, and temperaturedependent PA behavior. A derivative-free adaptive algorithm with dual-objective optimization is developed to track and compensate for temperature-induced PA variations using either digital predistortion (DPD) or RF predistortion (RFPD). In additions, a metalearning framework is incorporated to enable rapid convergence across multiple operating environments. Finally, circuit- and sys-tem-level design considerations are presented to facilitate practical and energy-efficient implementations.
Future wireless systems are expanding toward multi-gigahertz (GHz) bandwidths and sub-terahertz (THz) frequencies. Conventional solutions struggle with high sampling rates, strong nonlinearities, and the diminishing efficiency gains of analog circuits in complementary metal-oxide-semiconductor (CMOS) technologies. Wideband radio-frequency (RF) architectures require a new signal representation and processing paradigm to address these challenges, enabling energy-efficient wideband access and linearization. The Walsh sequency domain offers such an opportunity: its orthogonal basis enables highly parallel and energyefficient wideband operations, reducing RF signal-processing complexity while remaining fully compatible with CMOS technologies. Operating directly in the Walsh domain allows compact implementations of RF conversion, channelization, and nonlinear compensation. These capabilities have been experimentally demonstrated through proof-of-concept integrated circuits in CMOS fully depleted silicon-on-insulator (FDSOI) technologies, including GHz-range RF conversion, digital pre-distortion (DPD), and channel-aggregation techniques. Furthermore, a Walshnative end-to-end wireless autoencoder shows improved robustness to amplifier nonlinearities while benefiting from reduced sampling requirements. Walsh-based RF processing opens a new design space for multi-GHz bandwidth, energy-efficient, and hardware–algorithm co-design in next-generation artificial intelligence (AI)-assisted communication systems.

Digital Group Therapy (DGT) combines clinically-led group psychotherapy with continuous multimodal sensing, edge AI analytics, and online interaction platforms. This article synthesizes five perspectives presented at the IEEE CASS Workshop on Digital Group Therapy: neuro-dynamic modeling of group processes, cognitive workload management, next-generation edge-AI wearables, game-theoretic modeling of group behavior, and physics-inspired models of social interaction (sociophysics/social physics). We frame DGT as an open, multi-layer system of systems in which neural, physiological, cognitive, and social dynamics co-evolve under continuous feedback. We then connect this framework to recent evidence on online and mixed-reality group therapy and internet-delivered Cognitive Behavioral Therapy (CBT), and to classical and modern work in sociophysics and opinion dynamics. The resulting architectural view reveals concrete circuits-and-systems challenges in scalable signal acquisition, robust edge intelligence, human-in-the-loop adaptation, incentive design, and validation of closed-loop DGT interventions.
Triboelectric nanogenerators (TENGs) are attracting increasing attention as viable power sources for self-powered systems, due to advantages such as material and form-factor versatility, compatibility with low-frequency mechanical stimuli, and scalable, low-cost fabrication. Unlike conventional harvesters, TENGs exhibit two device-level characteristics that critically shape interface-circuit design: (i) a time-varying internal capacitance that induces a strongly dynamic source impedance, and (ii) a significantly high effective source impedance that yields very high open-circuit voltages at low currents. These characteristics directly affect impedance matching, rectification, voltage conversion, and maximum power point tracking (MPPT) strategies for maximum power transfer. While TENGs and piezoelectric energy harvesters (PEHs) share similar lumped electrical models, the time variance and voltage/current operating regime of TENGs fundamentally limit the portability of PEH-oriented power transfer methods. This paper provides two contributions. First, we introduce a figure-of-merit (FoM) that serves as an energy-extraction coefficient: the fraction of the ideal maximum power of the TENG device (under instantaneous impedance tracking) that appears at the rectifier input, typically the first stage of a power management unit (PMU). The FoM exposes losses arising from mismatch at the device-PMU boundary, thereby helping circuit designers localize dominant loss mechanisms (e.g., impedance mismatch, rectifier topology or suboptimal MPPT policies) and guiding device researchers to prioritize physical parameters (e.g., dielectric thickness, displacement, electrode area) with explicit awareness of interface constraints. Secondly, we conduct a thorough evaluation of the suitability of advanced PEH-derived methods, such as rectifiers (both passive and active configurations), DC-DC conversion, and MPPT, for application to TENGs. We derive theoretical upper bounds on extractable power for representative rectifier families under TENG-specific operating conditions, and we analyze technology-imposed voltage limits and their implications for architecture and control. We also survey recent TENG demonstrations together with their PMU interfaces and interpret reported performance through the proposed FoM. Overall, the analysis highlights that the unique characteristics of TENGs and technology limits for the voltages must be explicitly accounted for while developing interface circuits to realize maximum power extraction. This process can significantly benefit from coordinated device-circuit co-design via system-level metrics such as the proposed FoM.
