New Trends in High-Dynamic Range Analog-to-Digital Converters

This lecture by Prof. Satish Mulleti from IIT Bombay explores emerging trends in high-dynamic range analog-to-digital converters (ADCs). Discover the principles of modulo-folding ADC architectures, a promising alternative for digitizing high-dynamic range signals using low-dynamic range ADCs with a non-linear modulo operation. Learn about the mathematical framework of folding operations, various unfolding algorithms, and their relationships to classical techniques like delta modulation and sigma-delta modulation. The talk covers practical hardware considerations, power consumption trade-offs, and includes a case study on linear digital communication problems with quantitative results. Prof. Mulleti brings extensive experience from his work at ISRO, TCS Innovation Labs, IISc Bangalore, Technion, and Weizmann Institute of Science to this comprehensive exploration of ADC technology that serves as a critical interface between analog signals and digital processing systems.
