摘要

本論文的目標在於利用switched resonator的觀念來完成設計一可同時在 2.4/2.5/5/5.2GHz 多頻操作的壓控振盪器 (VCO)，並且在可調範圍及功率消耗的考量上取得一個很好的平衡點。在利用ADS模擬的過程中，皆是利用台積電所提供的 0.18µm V5 CMOS model 來完成的。此一多頻壓控振盪器操作在 2.4GHz , 2.5GHz, 5GHz 以及 5.2GHz 時，其 1MHz offset 的相位雜訊分別為–119 , –113 , -107 和 -101 dBc/Hz；同時在功率消耗表現上都大約是3.36mW。

This thesis presents the design of a switched resonator multiband VCO which allows better trade-off between tuning range and power consumption. Based on TSMC 0.18µm V5 CMOS technology, the multiband VCO operates near 2.4GHz , 2.5GHz , 5GHz and 5.2GHz with phase noise of –119 , –113 , -107 ,and -101 dBc/Hz at a 1MHz offset and ~3.36mW power consumption ,respectively.
