Abstract
A method for compensating non-linearities of a read signal generated by a variable-capacitance inertial sensor including a first fixed electrode and a second fixed electrode and a mobile electrode, which is spatially arranged between the first and second fixed electrodes and is capacitively coupled to the first and second fixed electrodes, said method comprising the steps of: acquiring the read signal; identifying a first linear component and at least one first nonlinear component of the read signal; a generating a compensated output signal by subtracting the first nonlinear component from the read signal.
