This work's power management circuit (PMC) employs optimum power point (OPP) instead of conventional maximum power point (MPP) extraction from the thermoelectric generator (TEG) for efficient source to load energy transfer. Based on postlayout verification of the TSMC 180‐nm deep submicron model, this PMC generates above 100
W of power with a regulated output of 2.5 V within 40 ms from 285‐mV cold‐start...
This paper provides a comparison of low voltage design strategies in charge pumps that may be used with micro-power energy harvesters. The focus is on low input voltage (< 500 mV) for possible cold start in monolithic integration. An overview of published low voltage techniques in charge pump designs are presented in four perspectives: body effect, gate voltages, MOS threshold voltage and power...
This paper presents a comparison of standard topologies for AC-DC converters within micropower energy harvesting systems. The focus is on low input voltage (< 1 V), low input frequency (< a few kilohertz), ultra-low power consumption (nanowatts to microwatts), and fully integrated inductor-less cold start topologies. These standard topologies are compared in terms of PCE (power conversion efficiency),...
