Optimization of Voltage Doublers for Energy Harvesting Applications [PDF]
IEEE Sensors Journal, 2013 Energy harvesting is increasingly enabling the expansion of wireless sensor networks in challenging applications by replacing batteries in low power sensors. Many forms of energy harvester suffer from low output voltage which can be partially compensated for by the use of a Cockcroft-Walton voltage doubler ahead of a dc-dc converter. Impedance matching
