Session 19 overview: Sensors and interfaces: Analog subcommittee

Abstract

This session highlights the advances in state-of-the-art temperature, current, physical and chemical sensors. Three energy-efficient CMOS temperature sensors with the best figures of merit down to 34fJ·K2 are reported. Two current sensors (Papers 19.4 and 19.5) are presented, one demonstrating a high room-temperature gain accuracy with a ±4A input range, while the other shows a 160dB DR biosensor readout with 7ppm INL. An energy-efficient pressure-sensing system (Paper 19.6) and a high-resolution readout IC (Paper 19.7) are also reported. An energy-efficient CO2 sensor achieving 2x better resolution (94ppm) and >10x lower energy consumption (12mJ/meas) than the prior art is also described (Paper 19.8).
