A Capacitive Pressure Sensor Interface

Low Drift, Wireless Temperature Sensor for Harsh Industrial Applications

In this thesis, a stand-alone, battery powered, wireless temperature sensor that can be used for diagnostic purposes in harsh industrial environments, including magnetic interferences and very low pressure (vacuum), is presented. Being easily mountable and removable during machine stoppage, this autonomous temperature sensor can be used at any...

Energy-Efficient Capacitive-Sensor Interface Based on A Multi-Slope ADC

This thesis presents an energy-efficient capacitive sensor interface based on a multi-slope analog-to-digital converter (ADC). This highly stable capacitance-to-digital converter (CDC) utilizes precision resistor as reference components. By utilizing a multi-slope analog-to-digital converter, the conversion time of this design is reduced down to...

A ratio metric analog-to-digital converter for eddy current displacement sensors

Displacement sensors are widely employed in industry for measuring position and movement of objects as well as for measuring other physical quantities like pressure, acceleration, etc., which can first be converted into movement. This thesis describes the implementation of a ratio metric analog-to-digital converter (ADC) for an eddy current...
