Abstract
A method for determining characteristic parameters of an electrostatic actuation oscillator, where the method includes generating a first excitation voltage defined as being the sum of a first sinusoidal voltage and a voltage pulse; applying the first excitation voltage at the input of the oscillator; acquiring in the time domain a first response voltage present at the output of the oscillator when the first excitation voltage is applied at the input of the oscillator; obtaining, by transformation in the frequency domain, a first amplitude spectral density of the first response voltage; determining the characteristic parameters of the oscillator from the first amplitude spectral density.
