The paper presents a power conditioning circuit (PCC) for an autonomous low power system in package (SiP) based on harvesting energy from vibrations. This self-powered system would be placed in indoor environments. The electromechanical transduction is performed using a low-cost commercial piezoelectric product, working at low frequencies and with voltages up to 2.5 V. The final designed IC has been tested and described in detail.
