Session 31 Overview: Analog Techniques Analog Subcommittee

Analog techniques continue to push the frontiers of precision, power, and performance. This year’s edition features two amplifiers and two accurate, temperature insensitive frequency references. The first paper describes a closed-loop, filter-less Class-D headphone amplifier that achieves the best output efficiency with low-power operation. The second paper pushes the state-of-the-art with the highest energy efficiency and lowest area. The third paper describes another low-power, low-area frequency reference that requires only a single-point trim to cover the entire industrial temperature range. Lastly, the final paper achieves the lowest chopper-induced intermodulation distortion (IMD) of -125.9dB ever reported.
