Abstract
A magnetic field sensor includes a die and a current generator in the die. The current generator generates a driving current. A Lorentz force transducer is also formed in the die and coupled to the current generator to obtain measurements of a magnetic field based upon the Lorentz force. The magnetic field has a resonance frequency and the current generator drives the Lorentz force sensor with the driving current having a non-zero frequency different from the resonance frequency.
