A Simultaneous Wireless Power and Data Transfer IC Using a Capacitive-Inductive Channel for Power-Data Delivery or Output Voltage Control

This thesis presents a Simultaneous Wireless Power and Data Transfer (SWPDT) IC using a Capacitive-Inductive (CI) Channel for power-data delivery or output volt- age control. In recent years, SWPDT systems have become increasingly important due to their ability to eliminate the need for wires and cables, making it easier to charge and communicate with devices. This can be especially important in applica- tions, such as healthcare or industrial automation, where wires can be inconvenient or even dangerous. However, SWPDT systems described in literature encounter challenges including the trade-off between power efficiency and data rate, inter- ference between data and power signals, and increased system size and complex- ity. These challenges are amplified under medium to high power conditions. To overcome these limitations this thesis presents a SWPDT IC tailored for medium- power industrial applications (e.g. collaborative robots) employing a CI-Channel. The power-data channel was designed, simulated, and characterized through mea- surements. The proposed SWPDT IC was designed, simulated and fabricated in 130-nm BCD technology. The project conception, design, layout and testing phases are described in detail and supported by simulation and measurement results.
