В статье предложена разработанная методика автоматизированного синтеза топологий интегральных СВЧ LC-фильтров с минимизацией потерь в полосе пропускания путем минимизации длин межсоединений и поиска оптимальных топологий проводников, катушек индуктивности и конденсаторов. Предложены алгоритмы минимизации потерь и минимизации длины межсоединений LC-фильтров. Оптимизация топологий проводников, катушек индуктивности и конденсаторов происходит на основе верифицированных в кремнии моделей, учитывающих основные характеристики и ограничения технологического процесса, скин-эффект, краевые эффекты, влияния подложки и переходных отверстий. На основе методики разработана САПР в ПО MathCAD, применение которой позволило сократить время проектирования интегральных LC-фильтров до десятков минут, уменьшить потери в полосе пропускания фильтров на 1,1–2,7 дБ, увеличить крутизны фронтов и спадов АЧХ на 47–267 дБ/дек.

The paper proposes the developed technique for automated synthesis of integrated microwave LC filter layouts with passband losses minimization by minimizing interconnection lengths and searching for optimal layouts of conductors, inductors, and capacitors. Algorithms for minimizing losses and length of LC-filter interconnections are proposed. The layouts of conductors, inductors, and capacitors are optimized based on silicon-verified models that take into account the main characteristics and limitations of the process, skin effect, edge effects, substrate and via influences. The CAD is developed in MathCAD software based on the proposed technique. The use of CAD made it possible to reduce the engineering time for integrated LC-filters to tens of minutes, reduce the filters passband losses by 1,1–2,7 dB and increase the AFCs gain slope by 47–267 dB/dec.
