Abstract

A sensor circuit and a method for compensating for temperature changes are provided. In accordance with an embodiment, sensor circuit includes at least one sensor for determining a measurement variable; a heating structure; and at least one compensation circuit. The compensation circuit is configured to acquire information about a temperature change in an environment of the sensor, and to counteract a temperature change in the sensor on the basis of the information by driving the heating structure.
