Abstract

　入力端子２、素子４ａ、４ｂ、４ｃ、４ｄ、負荷５の接続トポロジーを、電卓やデジタル時計などの数字の表示に適用される「７セグメントディスプレイ」状にする。すなわち、横方向に延びる３つのセグメント中の、最上部と最下部のセグメントに入力端子２を割り当て、縦方向の４セグメントのいずれか１つに負荷５を割り当て、残りの縦方向の３セグメントと横方向の１セグメントに素子４ａ、４ｂ、４ｃ、４ｄを割り当てる。素子４ａ、４ｂ、４ｃ、４ｄは、それぞれ、０．４０３ｐＦのキャパシタンスを有するキャパシタ、８．９８１ｎＨのインダクタンスを有するインダクタ、０．５９７ｐＦのキャパシタンスを有するキャパシタ、８．２１６ｎＨのインダクタンスを有するインダクタである。この回路構成により、素子総数が４に減じられ低損失性が実現され、また、共振回路の排除と梯子回路の規模が縮小されることより、高安定なインピーダンス整合が得られる。
