Abstract
This thesis presents the design of integrated interface circuits for inductive resonant wireless power transfer (WPT) systems, targeting implantable medical devices (IMDs). IMDs require compact, high-efficiency, and robust wireless power solutions capable of adapting to link and load variations. This thesis systematically develops three receiver and system architectures: voltage-mode (VM), hybrid voltage-/current-mode (V/CM), and resonant-current-mode (RCM), to improve power conversion efficiency (PCE), voltage conversion ratio (VCR), and adaptability over state-of-the-art designs.
