Abstract

Fractional Open-Circuit Voltage (FOCV) - Maximum Power Point Tracking (MPPT) technology is a novel approach for optimizing energy harvesting in low-powered systems operating at 220 GHz, a challenging frequency range. This paper introduces FOCV as an efficient MPPT technique, utilizing fractional voltage measurements to determine the optimal operating point for energy extraction in 220 GHz multi solid-state circuits. By employing FOCV, the proposed energy harvesting system achieves enhanced power efficiency, making it suitable for applications with strict power constraints. Additionally, this paper addresses the electromagnetic interference (EMI) challenges associated with operating at such high frequencies, presenting mitigation strategies to ensure reliable and interference-free operation of the FOCV-based energy harvesting system in the 220 GHz multi solid-state circuits. The results demonstrate the effectiveness of the FOCV - MPPT technology in improving energy harvesting efficiency while minimizing EMI-induced performance degradation.
