IC~WiBES Lab’s First Full Test Chip

Dr. Abhishek Srivastava’s research group at IC~WiBES Lab, CVEST breaks the barrier! IIIT Hyderabad achieved a significant milestone by successfully designing and fabricating a test chip for the first time in 25 years. The project was supervised by Prof. Abhishek Srivastava of CVEST. The main IC designers are MS students at CVEST — Arpit Sahani, Srayan Sankar Chatterjee, Pranjal Mahajan, Anushka Tripathi, and Deeksha. The process of chip design and tape-out marks a crucial step in transitioning from theoretical designs to a manufacturable product, significantly advancing the institute’s technological capabilities. It’s crucial for bridging the gap between theoretical knowledge and practical implementation, enabling students and researchers to innovate, publish significant findings, and prepare for high-impact careers in the semiconductor industry.

The test chip was fabricated in TSMC 65 nm technology. The chip includes advanced components crucial for modern communications, such as mmWave (near 20 GHz) and Sub-6 GHz circuits, which include receiver front end circuits, frequency synthesizers modules such Oscillator, Delta Sigma Modulator (DSM), frequency dividers, and filter. These technological advancements are set to enhance the performance and efficiency of mmWave sensing, with potential impacts across healthcare systems.
