This work proposes an autonomous energy scavenger battery-free switching power supply. A piezoelectric transducer is used to get electric energy from a mechanical vibrating source. Piezoelectric device has been modelled by means of its equivalent electric resonant model. All system has been designed and then simulated at system level by means of SystemC-WMS environment. The device make use of a full digital controller based on a Dynamic OSR ΣΔ modulator.
