Original Kurzfassung:
Resonating sensors are used for measurement tasks
in a wide range of applications. Depending on sensor type
and operating conditions, the signals of these sensors are often
afflicted with unwanted components induced by parasitic
sensor effects or the implemented sensor interface. Especially
when using digitizing interface circuits it can be advantageous
concerning the utilizable resolution of the system to compensate
these parasitic signals before the analog to digital conversion. In
this contribution, a method of analog compensation for parasitic
signal components is presented, that is implemented in an largely
digital impedance analyzer circuit for resonating sensors.
