wide field of applications to guarantee human safety or better reliability in harsh industrial environments. The transfer of both data and power across an isolation barrier is often an essential requisite in these applications. While data transmission with galvanic isolation has been achieved through traditional optocouplers, capacitive coupling, or integrated transformers, transferring power across the isolation barrier presents several challenges regarding the size and the performance. Some of the state-of-the-art devices adopt post-processed micro-transformers [1], which use 6μm-thick plated Au for both the primary and secondary windings. The operating frequency of the integrated transformers is ~180MHz to achieve optimal
