MAGNETIC SENSOR INCLUDING A LORENTZ FORCE TRANSDUCER DRIVEN AT A FREQUENCY DIFFERENT FROM THE RESONANCE FREQUENCY, AND METHOD FOR DRIVING A LORENTZ FORCE TRANSDUCER

摘要

A magnetic-field sensor, including: a die, a current generator in the die. The current generator generating a driving current. A Lorentz force transducer also in the die and being configured to obtain measurements of magnetic field based upon the Lorentz force is coupled to the current generator. The transducer having a resonance frequency. The current generator is such that the driving current has a non-zero frequency different from the resonance frequency.

1. A magnetic-field sensor, comprising:
a die; a current generator in the die and configured to generate a driving current; and a first Lorentz force transducer in the die, coupled to the current generator, and having a first resonance frequency, the current generator being configured to generate the driving current with a non-zero frequency different from the first resonance frequency.
