Wireless Indoor Climate Sensor: Implementing the Control Unit at Ultra Low Power

With the completion of the MIST1431 multi sensor IC a demonstrator developed by the Electronic Instrumentation Laboratory of Delft University of Technology and NXP, a demonstrator that shows the capabilities of the MIST chip was needed. This thesis describes the implementation of the control unit, which has to control the MIST chip and wireless...

Energy-efficient readout of resonant sensors

This thesis discusses the theory, architecture and circuit design and measurements of an ultra-low-energy prototype interface circuit for a resonant gas sensor in standard 0.35-?m CMOS technology. A transient measurement method is used here. The resonant sensor is driven at a frequency close to its resonance frequency by an excitation source...
