技術說明

一種連結不同振盪訊號源並使其輸出訊號同步的方式。透過不同振盪訊號源電路之個別電源接地點先連結在一起，之後再以電感或任何傳輸線型式網路之電氣連結到外部電源的真實地端。藉此，不僅不同振盪訊號源之振盪頻率一致，同時相位也相同。更進一步，若不同振盪訊號源之自由振盪頻率或振幅可調，則可改變其中某一電路之自由振盪頻率或振幅大小，達成穩態振盪頻率一致，但相位互異之狀態是可掌握及產生的。既有作法採外加注入方式進行振盪源間輸出相位同步鎖定，而此方法為透過電源接地之安排達成各振盪源間輸出相位同步鎖定。 This invention is to connect different oscillation circuits and let the outputs of different circuits become coherent. The way is to attach all of the power supply ground-nodes of different oscillation circuits to be wired together first, and then connect the wired-node to real grounding terminal of external power source by inductor or transmission line network. By this way, not only the oscillating frequencies of different oscillation sources become identical, but also no phase difference exists between them. Furthermore, if the free running frequency and output amplitude is adjustable, a controllable phase difference can be achieved at steady state with the same oscillating frequency. Compared to the announced technologies which are mostly done by external injection locking, this method employs the arrangement of power supply grounding to have the outputs of the multi-oscillating sources coherent.
