本論文針對無線收發機前端元件之電壓控制振盪器(Voltage-Controlled Oscillator, VCO),研究如何最佳化設計與建立設計流程,並且將此兩種晶片實作與量測,進而降低電壓控制振盪器(VCO)之功率消耗與相位雜訊,使得整體通訊品質得以提升。
本論文呈遞一個低相位雜訊的互補式交叉耦合對電壓控制振盪器(VCO)之研製,設計應用於全球互通微波存取(World Interoperability for Microwave Access, WiMAX)系統,可在3.64至5.37GHz的頻率範圍內振盪。此振盪器係利用開關電容模組來切換八個頻段;此外,金氧半(Metal-Oxide-Semiconductor, MOS)可變電容用於微調頻率。此全積體化的振盪器提供優良的特性:頻寬可達1.73GHz,亦即調頻範圍為38%;在1.8伏特直流電源下,核心電路的消耗功率為13.7mW;在1MHz偏移下,所有的相位雜訊均小於-122dBc/Hz。此VCO晶片係由台灣積體電路公司之0.18μm 1P6M CMOS標準製程所製造,晶片的面積為0.96 × 0.83(mm2)。
本論文呈遞另一個應用於光通訊之低功率與低相位雜訊的電壓控制振盪器(VCO)。此呈遞的振盪器亦由台灣積體電路公司之0.18μm 1P6M CMOS標準製程所製造。振盪頻率的範圍從8.72到9.66GHz,頻寬可達0.94GHz。當振盪於9.46GHz時,量測1MHz偏移時的相位雜訊,可得-107.3dBc/Hz。在1.8伏特直流電源下,核心電路的消耗功率為6.7mW。此振盪器由電感電容諧振電路、互補式交叉耦合對、記憶性減少尾電晶體和輸出緩衝器所構成,此晶片的面積為0.69 × 0.56(mm2)。
This thesis studies how to optimize and how to establish the design procedure for voltage-controlled oscillator (VCO) lying in the front end of transceiver. This thesis promotes the good quality of communication by means of decreasing power dissipation and phase noise. Two kinds of chips with different band of voltage-controlled oscillator (VCO) were implemented. From the data between simulations and measurement of these chips shows good agreement.
This thesis presents one low phase noise of the complementary cross-coupled voltage-controlled oscillator (VCO), which oscillates at a range of 3.64∼5.37GHz for WiMAX(World Interoperability for Microwave Access). This VCO utilizes switching capacitor modules in which eight channels are able to be selected. Moreover, MOS varactors are used as fine tuning. The fully integrated VCO provides excellent performance. The bandwidth of frequency is 1.73GHz, that is, the tuning range is 38%. The power dissipation of the core circuit is 13.7mW under 1.8V supply and phase noises all are smaller than -122dBc/Hz at 1MHz offset. This VCO was made by TSMC 0.18μm 1P6M CMOS standard process and the chip area is 0.96 × 0.83 (mm2).
This thesis presents the other low power and low phase noise voltage-controlled oscillator (VCO) for optical communication. This proposed VCO is also made by TSMC 0.18μm 1P6M CMOS standard process. The range of oscillation is from 8.72 to 9.66GHz. At a frequency offset of 1MHz from the 9.46GHz carrier, the measured phase noise is -107.3dBc/Hz. The power dissipation of the core circuit is 6.7mW under 1.8V supply. The bandwidth of frequency is 0.94GHz. The VCO consists of the LC tank, the complementary cross-coupled pair, the memory-reduced tail transistors and output buffers. The chip area is 0.69 × 0.56 (mm2).
