Abstract

This paper presents an overview of resistor-based sensors, with a focus on their energy efficiency. First, the theoretical energy efficiency limit of resistorbased sensors is determined and compared to that of traditional BJT-based sensors. This is followed by a review of the different types of resistor-based sensors. Finally, the design of a high-resolution Wheatstone bridge sensor is discussed in detail. Read out by a continuous-time Delta-Sigma modulator, the sensor achieves stateof-the-art energy efficiency, with a resolution FoM of 10 fJ·K2, which approaches the theoretical energy efficiency limit.
