Abstract
An oscillator-based sensor interface circuit includes first and second input nodes arranged to receive first and second electrical signals representative of an electrical quantity, respectively; an analog filter; a first oscillator arranged to receive a first oscillator input signal and a second oscillator different from the first oscillator and arranged to receive a second oscillator input signal; a comparator arranged to compare signals coming from the first and second oscillators; a first feedback element arranged to receive a representation of the digital comparator output signal and to convert the representation into a first feedback signal to be applied to the oscillation means; a digital filter arranged to yield an output signal, being an filtered version of the digital comparator output signal; a second feedback element arranged to receive the output signal and to convert the output signal into a second feedback signal.
