Abstract

The invention relates to an electronic system for an accelerometer having a piezoelectric element and a first mechanical resonance frequency, comprising: a) a damping circuit configured to: —receive an acceleration signal from the piezoelectric element; —electronically dampen an amplitude of the first mechanical resonance frequency; and—generate a damped acceleration signal, b) an extender configured to: —receive the damped acceleration signal; —extend the frequency response; and—output an extended damped acceleration signal, wherein the extender is configured to have a first electronic anti-resonance frequency matching the damped first mechanical resonance frequency, and to have a frequency response between the first electronic anti-resonance frequency and a higher second frequency that is substantially opposite to a corresponding frequency response of the combination of the accelerometer and the damping circuit.
