Abstract

This article presents a dc-dc boost converter for energy harvesting. The time-domain maximum power point tracking (MPPT) technique implements to maximize the source's energy harvesting performance with no additional switch and time slot. Furthermore, it is implementing digital self-tracking zero current detectors for high efficiency. This dc-dc boost converter fabricates with a 180-nm CMOS process. The input voltage of the boost converter ranges from 0.2 to 0.7 V and generates an output voltage of 1.2 V. The total area of this converter with the MPPT operation is 600 μm × 475 μm. The measured power conversion efficiency of this dc-dc boost converter is 85.5%.
