This paper presents a fully autonomous integrated circuit for power conversion from multiple and heterogeneous energy harvesting transducers. Five input channel are dedicated to vibrational harvesting and exploiting multi-frequency operations. Additional four input channels are dedicated to manage DC sources with independent MPPT applied on each channel. A relevant feature of the design is the use of specific nano-power design techniques which reduce the converter quiescent consumption down to 40 nA/source and still keep energy conversion efficiency up to 82.8%. Only few external components are required: a capacitor for energy storage, an inductor and four capacitors for MPPT on DC sources.
