ABSTRACT:
A sigma-delta modulator comprising:at least one resonator (100a, 110b),a converter (120) to convert an analogue signal from the resonator into a digital signal with time information, anda feedback loop connecting an output of the converter to an excitation input of the resonator.According to the invention, at least one resonator in the modulator is chosen from among the group comprising mechanical, acoustic, electromechanical, electrostatic, optical and chemical resonators. Application to analogue-digital conversion, signal detection and signal generation.
