摘要

本論文分為三個部份，第一部份為X-Band 壓控振盪器設計，目的為研製一超低電壓和低功耗的12 GHz 壓控振盪器(Voltage-Controlled Oscillator, VCO)。本部份並探討壓控振盪器操作在低電壓下造成振盪信號的影響，且提出改善方式，讓振盪器電路得以在低電壓操作下，依然具有優異的效能。此電路使用台積電0.18-um CMOS製程。經由量測結果得知，當壓控振盪器的核心操作電壓為0.4 V時，其核心消耗功率僅為1.08 mW。當壓控振盪器操作於12.76 GHz時，距離載波1 MHz處量測到的相位雜訊為 -110.2 dBc/Hz。此壓控振盪器的調整頻率範圍為12.05 GHz至12.76 GHz (5.72 %)，晶片面積為0.795 × 0.745 mm2。
第二部份為無線射頻辨識系統於物流業之應用，在各行各業之物流系統中，需要一具快速、無線、遠距離之辨識物品運輸系統，故本論文以可遠距離讀取的超高頻無線辨識系統作物流運輸業之應用，並針對無線辦識系統做實際測量與評估。
第三部份為使用微控制器架構，利用序列週邊介面(Serial Peripheral Interface, SPI)通訊方式，實現具有多段存取功能的錄放音系統。此外，在錄放音系統上外接一音頻放大器，達到較大音量輸出，並且透過微控制器控制錄放音晶片改變輸出音量大小。

This thesis is divided into three parts. The first part is design a X-Band Voltage-Controlled Oscillator (VCO) which is an ultra-low voltage and low power 12-GHz VCO, and discuss about the effect of VCO’s oscillation signal at low operation voltage. Moreover, the way of improvement performance at low operation voltage have utilized in the VCO. The VCO made by TSMC 0.18-um CMOS process. After measurement, when the VCO operation voltage is 0.4 V which power consumption only 1.08 mW. And the measured phase noise is -110.2 dBc/Hz at 1-MHz offset from 12.76 GHz carrier. The VCO exhibits a tuning range of 5.72%. The VCO chip size is 0.795 x 0.745 mm2.
The second part is RFID application for goods transportation. In transportation system, which needs a fast, wireless and long distance identifiable transfer system of goods, so we choose UHF RFID system to apply on transportation system for long -distance identification. Moreover, this is measurement the field of identifiable range for UHF RFID.
The last part is using microcontroller (MCU) system by serial peripheral interface (SPI) communication to realize a recording system, and using a voice amplifier for big volume output. Besides, the MCU could control the recording chip to change volume output.
