About
Gourab Barik is a rising star in energy-efficient integrated circuit design, with a focus on low-power video processing for emerging sensor networks. His research targets the critical bottleneck of data volume in camera-based systems—from surveillance and healthcare to autonomous vehicles and robotics—by pioneering direct analog-to-compressed-domain conversion. Barik’s most notable contribution is the first-ever direct analog-to-MJPEG converter, demonstrated in a 65 nm CMOS chip that consumes only 2.02 mW while achieving 50 Mbps throughput. This work, published in 2023 and already garnering 6 citations, integrates a low-noise switched-capacitor MAC-quantizer with automatic calibration and a sparsity-aware ADC, eliminating power-hungry digital compression stages. By bypassing conventional gigabit-per-second data paths, his design enables real-time video compression at a fraction of the energy cost, a breakthrough for battery-powered sensor nodes. Barik’s innovations promise to reshape how video data is captured and processed at the edge, making high-quality imaging feasible in ultra-low-power environments. His work stands as a testament to the power of analog-circuit ingenuity in solving modern data deluge challenges.
