Abstract
Resonant sensors are used in a wide range of applications, e.g. as microbalances, chemical sensors in liquid and gaseous environments, and for physical property sensing of liquid and viscoelastic media. The signals obtained from these sensors are most often afflicted with unwanted or spurious components which, depending on sensor type and operating conditions, can be caused by parasitic sensor effects or by the implemented sensor interface circuit. Common ways of handling these effects by post-processing the sensor data usually reduce the dynamic range of the measurement interface due to the fact that a certain percentage of the input range is occupied by the unwanted signal components. In this contribution, a method of analog compensation for parasitic signal components is presented, which is implemented in a largely digital impedance analyzer circuit for resonating sensors.
