使用變壓器回授及正向基底偏壓壓控振盪器之研究

The study of using transformer feedback voltage control oscillator with forward body bias

指導教授 : 荊鳳德

摘要


本論文描述如何設計一個低電壓、低功率損耗及低相位雜訊的金氧半壓控振盪器。討論如何利用變壓器回授來增強電晶體的轉導以達到降低功率同時又拉大輸出擺幅的效果。使用基底偏壓後,又進一步的改善整個架構。此差動振盪器使用TSMC 0.18um CMOS製程並經由ADS momentum做EM模擬分析。在此設計一個操作10GHz的壓控振盪器,約有9.5GHz 頻率調整範圍,在振盪頻率距1MHz 頻偏下有-112.5dBc/Hz 的相位雜訊以及1.3mW的功率消耗。

Design of low-voltage, low-power CMOS Voltage-Controlled Oscillator(VCO) will be investigate in this thesis. We will discuss how to use transformer feedback to enhance transconductance to reduce power consumption and achieve high output swing at the same time. After using forward body bias, we improve the structure further. The differential VCO is implemented using TSMC 0.18um process. The EM simulation results with ADS momentum. A designed 10GHz VCO achieves a turning range of 9.5GHz, and phase noise about -112dBc at 1MHz offset frequency with power consumption 1.3 mW.
