Abstract: An electronic measuring device for measuring a physical parameter includes a differential analogue sensor formed from two capacitances—an excitation circuit of the differential analogue sensor providing to the sensor two electrical excitation signals which are inverted—a measuring circuit which generates an analogue electrical voltage which is a function determined from the value of the sensor, and a circuit for compensating for a possible offset of the sensor, which is formed from a compensation capacitance, which is excited by its own electrical excitation signal. The excitation circuit is arranged in order to be able to provide to an additional capacitance of the compensation circuit its own electrical excitation signal having a linear dependence on the absolute temperature with a determined proportionality factor in order to compensate for a drift in temperature of an electrical assembly of the measuring device comprising at least the compensation capacitance.
