摘要

随着始终在线的无线传感节点的出现，需要用于低于1w应用的AC/DC电源转换解决方案。现有的方法对于这样的输出负载并不有效，因此需要提供新的解决方案。在本文中，我们提出了一种针对输出负载高达500 mW的运行进行优化的解决方案，而高效率和接近零的空载消耗一直是我们的首要设计目标。所提出的设计在高压CMOS工艺中实现，晶体管级仿真结果表明，所提出的解决方案的性能优于现有的解决方案。

High side power MOSFET switch driver for a low-power AC/DC converter

With the emergence of always-on wireless sensing nodes, AC/DC power conversion solutions for sub 1 W applications are required. Existing approaches are not efficient for such output loads, and therefore, new solutions need to be provided. In this paper, we propose a solution that is optimized for operation with output loads up to 500 mW, while high efficiency and close to zero no-load consumption have been our foremost design goals. The proposed design is implemented in a high-voltage CMOS process and transistor level simulation results show improved properties of the proposed solution over the existing ones.
