A Fully Integrated Switched-Capacitor Based AC-DC Converter for a 120VRMS Mains Interface

A fully integrated AC-DC power converter inter- facing the 120VRMS mains and fabricated in 0.35 μm-CMOS is presented. The converter uses a variable voltage division approach in order to step down the high input voltage while increasing the power density. The design includes customized AC-switches and a high-voltage capacitor and achieves an output power of 15.16 μW at an efficiency of 80.7 % on 9.8 mm² .status: Published onlin
