Voltage calibration of BJT-based temperature sensors

Nowadays, the BJT-based temperature sensors have occupied the majority of the market. Due to process spread, BJT-based temperature sensors usually requires calibration. Currently, thermal calibration is the only method. However, it is usually costly and time consuming. In this paper, a new calibration method called voltage calibration is...

An Energy-Efficient Reconfigurable Interface for Resonant Sensors Based On Ring-Down Measurement

This thesis discusses the theory, architecture design, circuit design and measurements of an ultra-low-energy reconfigurable interface circuit for resonant gas sensors. This interface circuit employs a transient measurement method. The resonant sensor is driven at a frequency close to its resonance frequency by an excitation source that is...
