Abstract
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 P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">abs</sub> and the load resistance R <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">L</sub> . To establish lookup tables, an improved rectification model is developed, allowing for accurate data generation at any specific coordinate (R <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">L</sub> , P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">abs</sub> ). High-quality lookup tables are thus established with the equidistant data over the (R <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">L</sub> , P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">abs</sub> ) plane. Based on the lookup tables, the optimal operating point (R <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">L</sub> , P <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">abs</sub> ) 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.
