Popis: A simple and versatile electronic interface circuit for sensors is presented. The novel interface circuit is based on a relaxation oscillator in differential configuration. In such a configuration, the sensitivity is strongly increased and compensations are made possible. It can be applied to resistive, capacitive and inductive sensors or detectors. Experimental and simulation results confirm the theory built up. High sensitivity is measured. Non-idealities of electronic components set the limit of attainable sensitivity.
