Frontiers in Analog and Mixed-Signal IC Innovation for Ultra-Low-Power Applications

Power-constrained applications such as wearable and implantable devices demand extreme energy efficiency without compromising performance, robustness, or reliability. In these systems, analog and mixed-signal integrated circuits (ICs) play a vital role in interfacing with the physical world, acquiring signals, enabling edge-level data processing, and wirelessly transmitting data, while operating under strict power, area, and thermal constraints. Circuit designers face new trade-offs between precision, speed, and power efficiency. This talk will explore recent advances in low-power analog and mixed-signal circuit architectures tailored for energy-limited environments, including innovations in high-precision front-end interfaces, high-current stimulation drivers, and ultra-low-power backscatter communication. The discussion will then extend to system-level optimization strategies that enhance energy-efficient operation in power-constrained devices. Practical examples will be presented to illustrate how low-power IC solutions can unlock new opportunities for the next generation of resource-aware systems.
