Advances in State-of-the-Art in Smart Sensor Signal Conditioning

This paper overviews the requirements for calibration and compensation of piezoresistive sensors. It characterizes the evolution of sensor signal conditioning technology over the last decades, with the focus on smart transducer technology. It discusses in detail an advanced design of the Analog Sensor Signal Processor from one of the Silicon Valley start-up companies. Finally it introduces the emerging IEEE-P1451 Standard for Smart Transducer Interface for Sensors and Actuators and characterizes its impact on smart sensor electronics.
