| 技術摘要 / Our Technology： |
本發明為一種應用於高頻段的環型耦合器，其係使用至少二個電晶體環狀連接，每一個電晶體配合共振器構成振盪源。因為本發明使用至少二個電晶體串接，所以本發明的開路迴授增益大於先前技術之交叉型耦合對振盪器的開路迴授增益。本發明可以降低高頻時電晶體增益不足，以及高基板損耗的問題。本發明的另一個特點在於電路佈局的對稱性，且無需額外的連接線，所以連接線的雜散效應都可以顯著地降低。
The present invention discloses a high-frequency ring coupled Quad comprising at least two transistors, which are cascaded to form a ring and bonded to resonators to form an oscillation source. The open loop feedback gain of the ring coupler of the present invention is higher than that of a conventional cross-coupled pair oscillator because the present invention adopts at least two cascaded transistors. The present invention can solve the problems of low transistor gain and high substrate loss occurring at a high frequency. The present invention has a fully symmetric circuit topology and is free of additional interconnections lines, which can obviously reduce the stray effect of interconnection lines.
