摘要: | 本論文分為6個章節,分別為:第一章為簡介短距離無線通訊系統的規格,和短距離無線接收機的系統規格,以及本論文各章節的概要內容。第二章提出以台積電矽鍺0.35微米製程和磷化銦鎵2微米製程製作的新式超寬頻低雜訊放大器,使用電容回授技術達成輸入端50歐姆的阻抗匹配和電感回授放大器達成超寬頻功率增益,討論其設計方法和實驗結果,並以理論分析分別解釋了超寬頻輸入阻抗匹配、功率增益、及雜音指數等特性參數。第三章和第四章為發明兩種可應用在無線區域感測網路中新式開關移鍵調變單晶片接收機,以聯華電子CMOS 0.18微米製程實現,操作電壓為0.5伏特,而功率消耗僅為3毫瓦,只需數十顆電晶體可同時完成接收和解調的功能,此晶片以電路板製成無線接收模組,以一0.5伏特太陽能電池供電,可在數公尺內接收無線電波。此外,發明一共用同一偏壓電流的低功率接收機前端電路,以台積電矽鍺0.35微米製程製作,此前端接收機達到低功率消耗、高電壓增益和低雜音的性能,可應用於無線區域感測網路。第五章和第六章提出以人體皮膚作為通訊傳輸介質的「有線個人區域網路」構想,實現一上身通訊網路系統。用於傳輸之裝置乃自行開發之系統單晶片(SoC),包含ASK接收機、ASK發射機及微處理器。本系統單晶片亦嵌入一專為人體傳輸網路(intra-body network)設計之特殊通訊協定,亦即身體各處可遍布多個此種單晶片,而由一控制中心來控制其行為。 The dissertation comprises contents of ultra-wideband (UWB) low noise amplifiers (LNAs) by SiGe and InGaP HBT technologies for UWB communication, low-power receivers and a front-end receiver for wireless local sensor networks (WLSN), and a system on chip (SoC) with an embedded communication protocol for biomedical body sensor network (BBSN). In the chapter 1, a brief introduction of wireless standards, receiver specifications, and dissertation organizations is presented. In the chapter 2, we reported a SiGe HBT UWB LNA, achieved by a newly proposed methodology, which takes advantages of the Miller effect for UWB input impedance matching and the inductive shunt-shunt feedback technique for bandwidth extension by pole-zero cancellation. Besides, an InGaP/GaAs UWB LNA using same methodologies is also presented. In the chapter 3, a low voltage (0.5 V) low power (3.1 mW) on-off keying (OOK) miniaturized monolithic receiver implemented in 0.18 μm CMOS technology for WLSN is implemented. Moreover, human electrocardiography (ECG) transmission was demonstrated that the receiver with the solar cell supply can receive biomedical signal well wirelessly. Besides, a low-power, current-reuse front-end receiver using SiGe BiCMOS 0.35 μm technology is first presented. In the chapter 4, a 0.5 V 2.9 mW monolithic self-mixing receiver using 0.18 μm CMOS process is reported. Low voltage/power operation is achieved by using a simple circuit topology along with low threshold voltage (0.2 V) transistors. In the chapter 5, a low-power monolithic biomedical SoC consisting of a receiver, a transmitter, a MCU, and an ADC, implemented in a 0.18 uW. |
