Abstract
A circuit for biasing and reading out a bridge sensor structure comprises at least two pairs of connection terminals. The circuit comprises an excitation signal generator for generating an excitation signal for biasing and/or exciting the bridge, in which the excitation signal is provided as a non-constant periodic continuous function of time, and a detection circuit for obtaining the sensor signal from the bridge sensor structure by electrically connecting the detection circuit to any pair of connection terminals while applying the excitation signal to another pair. The circuit comprises a switch unit for switching the electrical excitation signal and for switching the detection circuit. A controller controls the switch unit to switch the first pair from being connected to the excitation signal generator at a time when the generated excitation signal is in a predetermined signal range where the excitation signal value is substantially equal to zero.
