Implementation of a Low Power Boost Converter in-line with a Rectifier for RF Energy Harvesting Application

Authors: , ,

Abstract: With the growing requirement of RF coverage, harvesting and management of the associated power along with the conversion of energy into appropriate form is essential. It makes the design of relevant rectifier systems an important aspect. Attainment of a high percentage conversion efficiency (PCE) at lower input power, may not be enough if it is not supported by a DC-DC converter. A boost converter plays a significant role for managing the harvested energy for further utilization. This paper presents a simple, low power, high frequency boost converter for specific target storages or applications. It achieves a peak efficiency of 93% at a very low input power of -12dBm with the use of only two MOSFETs and for smaller value of inductance making the design feasible. Moreover it achieves a very good transient settling time of 5.5μs .
