Abstract
Description
近代の集積回路(IC)はしばしば、十分にギガヘルツ範囲内の周波数で動作することが求められる。10GHz以下の周波数に関しては、許容可能な性能を提供するさまざまな回路構造が公知である。たとえば、好適に高い品質(Q)値を有する、10GHz以下で動作する公知のインダクタ−コンデンサ(LC)回路構造を実現することができる。これらのLC回路構造はフィンガコンデンサを組入れている。
回路は、第1のバス配線が第1の複数のフィンガ素子に結合され、かつ第2のバス配線が第2の複数のフィンガ素子に結合される第1のフィンガコンデンサを含む。第1のバス配線は第2のバス配線に平行である。回路は、第1のレグが第1のバス配線および第2のバス配線に垂直に向けられるインダクタも含む。インダクタの第1のレグは第1のバス配線の中央に結合される。
開示は新規の特徴を規定する請求項で結ばれるが、図面とともに説明を検討することによって本明細書中に記載のさまざまな特徴がより十分に理解されると考えられる。この開示内に記載のプロセス、機械、製造、および任意のその変形は例示の目的のために与えられる。記載の任意の特定の構造的および機能的詳細は限定と解釈されるべきではなく、単に請求項の根拠として、および事実上任意の適切に詳述される構造において記載の特徴をさまざまに用いることを当業者に教示するための代表的な根拠として解釈されるべきである。さらに、この開示内で用いられる用語および文言は限定を意図するものではなく、むしろ記載される特徴の理解可能な説明を提供することを意図する。
