New energy-efficient interface IC to provide voltage regulation for energy harvesters

At ISSCC 2013, Holst Centre and imec have presented an innovative method for the power-management of piezoelectric energy harvesters. The proposed interface IC provides energy-aware supply voltage regulation from cold start with a power consumption of less than 140nW. A power efficiency of 90 to 94% is achieved in a wide power range of 1
