Abstract
A sensor includes a transducer that provides a sensed signal to a signal processing device. The signal processing device switches the operating mode as a function of frequency, such that the switching device is operated in the switched operating mode at low frequencies and in the continuous operating mode at high frequencies. In a preferred embodiment, the transducer is a Hall effect sensing device.
Claims14
A sensor, comprising:
- a transducer device to convert a sensed physical quantity into a corresponding electrical measurement signal;
- a signal processing device that receives said electrical measurement signal and generates a offset compensated sensor output signal based upon said measurement signal, said signal processing device including
- (i) at least one switching device for offset compensation;
- and
- (ii) means for switching the operating mode of said switching device as a function of frequency, such that said switching device is operated in a switched operating mode at low frequencies and in a continuous operating mode at high frequencies.
