本論文研究內容為使用TSMC 0.18µm CMOS 製程技術進行低雜訊壓控振盪器積體電路之設計，在以不同的低電壓供應條件下，設計供IEEE802.11a頻段使用之振盪器。本文主要針對振盪器之相位雜訊進行改善，同時希望達到低電壓操作、更寬的頻率調整範圍、更小的晶片面積以及更低的功率損耗為目標。本電路在1.8V電源的條件下，其頻率調諧範圍從4.965GHz到5.955GHz，控制電壓在0.1V時，其相位雜訊為-121.3dBc/Hz@1MHz，功率損耗為12.6mW。若將電壓調降到1.2V，功率損耗為3.33mW。

The thesis research is using TSMC 0.18µm CMOS process technology to design low phase noise voltage controlled oscillator. To design the oscillators under the different power supplies is used for IEEE802.11a. Its main improvement is on the phase noise of the oscillator. Simultaneously we hope it can achieve the goal for low voltage operation, wider frequency tuning range, smaller chip area, and lower power consumption. The circuit operates at 1.8V, its frequency tuning range is from 4.965GHz to 5.955GHz. When controlled voltage operates at 0.1V, its phase noise is -121.3dBc/Hz@1MHz, and its power consumption is 12.6mW. If we turn down the supply voltage to 1.2V, its power consumption is 3.33mW.
