本論文主要分成三個主題。第一個部份是環形壓控振盪器的理論架構與溫度補償的晶片設計實作與量測，第二個部份是2.4GHz電感諧振槽壓控震盪器的晶片設計實作與量測，第三個部份是2.4GHz 除頻器的晶片設計實作與量測。除了2.4GHz 除頻器所使用的是UMC 0.18um COMS 1P6M製程，其餘的電路所使用是TSMC 0.35um CMOS 2P4M製程，且利用Spectre RF軟體來進行電路模擬。未來目標希望能整合振盪器與除頻器的概念，且能使用於PLL電路或相關的應用，使其能呈現出更好的電路特性。

This thesis is mainly composed of three topics. The first topic is the design, implementation and measurement of a ring voltage-controlled oscillator (VCO) with temperature compensation structure. The second topic is the design, implementation and measurement of a 2.4GHz LC-tank VCO. The third topic is the design, implementation and measurement of a 2.4GHz frequency divider. In first two circuits of whole three designs, ring VCO with temperature compensation structure and 2.4GHz LC-tank, they are fabricated by TSMC 0.35um CMOS 2P4M, except the 2.4GHz frequency divider is fabricated by UMC 0.18um COMS 1P6M. All circuits in this thesis are simulated using by Spectre RF CAD. In future work, we hope to integrate the concepts of oscillator and divider, and could be utilized in the phase-locked loop and so on.
