Abstract
In this paper, a new tunnel FET (TFET)-based power management circuit (PMC) is proposed for weak dc energy harvesting sources. Thanks to their particular carrier injection mechanisms, TFETs can be used to design efficient energy harvesting circuits by enabling the power extraction from sources which are not only at very low voltage levels (sub-0.1 V) but also at very low power levels (a few nW). As TFET devices are designed as reverse-biased diodes, changes in conventional circuit topologies are...
