操作於次十億赫茲頻帶之脈衝無線電式極寬頻傳輸器設計

本作品中實踐了兩個操作於四億赫茲且低功率消耗之脈衝無線電式極寬頻無線發送機，適用於低功率損耗且高資料傳輸量之應用。在第二章中會先介紹關於極寬頻技術的基礎及相關規範，並同時介紹幾種比較常見的脈衝無線電式極寬頻無線發送機架構。在第三章中會先介紹一個採用開關式調變之發送機、而在第四章中會介紹一個支援多種調變之無線收發機。第五章則是結論與未來可以努力的方向。　　在提出的開關式調變脈衝無線電式極寬頻無線發送機中，採用了以有限脈衝響應系統為基礎的脈衝產生器架構。當一個很窄的脈衝進入脈衝產生器後，會產生一個具有較佳頻譜效應的輸出訊號。此發送機是使用台積電0.18微米製程設計，消耗功率為1.67 mW、最大資料傳輸速率為每秒1億位元。　　在第四章中所提出的脈衝無線電式極寬頻無線收發機是採用波形合成的技術產生輸出脈衝。此架構省略了本地振盪器的輸出功率、但輸出波形就易受到雜訊影響，因此在此架構中，提出了一組額外的脈衝寬度校正電路做脈衝寬度的校正。此發送機在1伏特的供應電壓下消耗525.38 uW的功率，最大資料傳輸速率可以達到每秒1億位元。

In this work, two low-power impulse-radio ultra-wideband (IR-UWB) transmitters operating at 400-MHz center frequency are designed for low-power, high-data-rate applications. The fundamentals and specifications are introduced in Chapter 2, along with the most commonly used architectures of the IR-UWB transmitter. One of the transmitters performs on-off keying (OOK) modulation and will be discussed in Chapter 3. The other one can modulate the signal with OOK, pulse position modulation (PPM), and binary phase shift keying (BPSK) will be discussed in Chapter 4. Chapter 5 shows the conclusions and future works. 　　The proposed OOK IR-UWB transmitter generates the pulse with finite-impulse- response-based (FIR-based) pulse generator. The narrow pulse enters the pulse generator, thus generating pulses with better spectral efficiency. The proposed design is fabricated in a 0.18-
