Rectifier design nowadays relies heavily on iterative optimization, which is prone to fall into local minima or end up with no solution. Such a procedure is time-consuming and requires lots of experience from designers. Guided rectifier synthesis with the least engagement of optimization is thus desired. In this article, a lookup-table-based automated rectifier synthesis method is presented. The lookup tables are essentially contour maps of the rectifier performance indicators on a 2-D plane of the absorbed RF power Pabs and the load resistance RL. To establish lookup tables, an improved rectification model is developed, allowing for accurate data generation at any specific coordinate (RL, Pabs). High-quality lookup tables are thus established with the equidistant data over the (RL, Pabs) plane. Based on the lookup tables, the optimal operating point (RL, Pabs) can be straightforwardly identified according to the requirement, facilitating the subsequent diode and topology selection and matching circuit design. The whole design flow is sequential and automated, only engaging fine-tuning in the final stage. Simulation and measurement results validate the proposed methodology.

基于查找表的自动整流器综合


如今的整流器设计严重依赖迭代优化，很容易陷入局部极小值或最终无解。这样的过程非常耗时，并且需要设计者大量的经验。因此，需要最少参与优化的引导整流器合成。在本文中，提出了一种基于查找表的自动整流器综合方法。查找表本质上是吸收射频功率 Pabs 和负载电阻 RL 的二维平面上整流器性能指标的等值线图。为了建立查找表，开发了改进的校正模型，允许在任何特定坐标（RL、Pabs）处生成准确的数据。因此，使用（RL，Pabs）平面上的等距数据建立了高质量的查找表。基于查找表，可以根据需求直接确定最佳工作点（RL、Pabs），方便后续的二极管和拓扑选择以及匹配电路设计。整个设计流程是连续的、自动化的，只在最后阶段进行微调。仿真和测量结果验证了所提出的方法。
