Abstract

millimeter wave radio frequency voltage controlled oscillators wireless energy transmission Integrated Circuits
This dissertation investigates the design and development of compact, frequency-reconfigurable RFICs engineered for two primary objectives: efficient energy harvesting and robust wireless communication. The research involves on developing circuits that can be frequency tuned to target multiple frequency bands. Such reconfigurability is critical for operating across multiple frequency bands, enhancing energy efficiency, and ensuring optimal performance. By enabling these circuits to adjust in real time, the work contributes to better utilization of scarce spectral resources, making the systems more versatile and capable of functioning in a broader range of scenarios. The key contributions of this dissertation are focused on: dual-band energy harvesting for wireless power transfer applications in ISM bands, triple-band oscillator design in K-Ka band, and strong interference cancellation in the L-band. There could be numerous applications of the techniques developed in this work, some of which are demonstrated here in this dissertation. Few more applications and suggestions for future research directions based on the proposed work are also outlined here.
