本論文主要目的是在研製12 GHz注入鎖定式壓控振盪器，為了實現該電路本論文所採用的架構是回授式振盪器。由於注入鎖定式壓控振盪器主要應用在自我注入鎖定雷達上，是該雷達的核心電路。為了提高雷達的感測靈敏度，本論文將設計重點著重在振盪器的注入鎖定範圍，嘗試各種實驗將振盪器的品質因子降低以提高鎖定範圍。
首先為了確定回授式振盪器的架構可以實現在12 GHz，並且擁有較高的注入鎖定範圍，所以先以2 GHz的頻帶作嘗試。為了瞭解回授式振盪器各個元件的關係，實驗的過程中皆以使用商用元件組成之振盪器為前置實驗。之後再將各個元件組合起來成一體化振盪器。
為了可以有效的提升注入鎖定式壓控振盪器的注入鎖定範圍，本論文針對相位雜訊與鎖定範圍的關係進行研究，在實驗中嘗試改變諧振器與電路的設計，以此改變諧振器的品質因子。最後藉由實驗的數據驗證振盪器的等效品質因子與相位雜訊、注入鎖定範圍的關係。

This thesis studied the injection-locked oscillator with operating frequency at 12 GHz. In the thesis, it used a structure of feedback oscillator to implement the circuit. Because the main application of injection-locked oscillator is used for the self-injection-locked radar, it is a critical component in the radar. In order to improve the sensing sensitivity of the radar, the main point of the circuit design for the oscillator in this thesis is the injection-locking range. Therefore, it will demonstrate some experiments and try to reduce the quality factor of the oscillator for increasing the locking range.
First, to ensure that the structure of feedback oscillator can be successfully implemented at the operating frequency of 12 GHz, it will first design the circuit at 2GHz. Besides, it used the commercial components to compose the oscillator as a preliminary experiment to realize the relations between every component in the circuit, and it will integrated every component into a circuit board as a oscillator afterwards.
Second, to effectively increase the injection-locking range of the injection-locked oscillator, it will focus the study on the relation between the phase noise performance and the locking range, and try to modify the circuit design for the oscillator to improve the quality factor. Finally, according to the experimental results, it will also verify the relation between the equivalent quality factor, phase noise and injection-locking range of the oscillator.
