使用3D電感之除二注入鎖定除頻器設計

為了解決Phoenix RC的問題，作者游御民 這樣論述：

在射頻積體電路(RFIC)中，頻率合成器扮演著重要的角色，其內部包含了相位偵測器(PFD)、充電幫浦(CP)、迴路濾波器(LF)、壓控振盪器(VCO)、除頻器(FD)。壓控振盪器需要低相位雜訊來避免相鄰雜訊訊號經由混波轉換的干擾，壓控振盪器的輸出在經由除頻器來達到降頻的工作，因此除頻器必須具有高的操作頻寬與頻率。而此論文主要研究鎖相迴路中的注入鎖定除頻器。首先，設計一個使用3D八字型電感之寬頻注入鎖定除二除頻器，使用台積電0.18μm CMOS製程，此除頻器使用電感並聯電路之寄生電容作為共振腔，以及使用電容交叉耦合作為負電阻產生震盪。注入主動元件之偏壓及電容交叉耦合對之主動元件閘極偏壓被使用

在調整除頻器的自振頻率。將此電路與其他使用八邊形電感之除頻器相比，使用八字形電感之除頻器有較低的EM幅射等級以及較小的EM雜訊接收敏感度。使用3D八字型電感作為共振腔之注入鎖定除頻器在輸入 0dBm時，鎖頻範圍為2.6至10.4 GHz(120%)，FOM值為13.6，功耗為8.8mW。接著，設計一個使用八字型變壓器的除二注入鎖定除頻器，使用台積電0.18 μm BiCMOS製程，此除頻器藉由相同磁場去耦合兩個子電路除頻器。高頻帶及低頻帶(子電路)使用八字型電感並聯電路之寄生電容作為共振腔，以及使用電容交叉耦合作為負電阻產生震盪。注入主動元件之偏壓及電容交叉耦合對之主動元件閘極偏壓被使用在調整

除頻器的自振頻率。將此電路與其他使用八邊形電感之除頻器相比，使用絞線變壓器之除頻器有較低的EM幅射等級以及較小的EM雜訊接收敏感度。此注入鎖定除頻器在輸入0dBm時，鎖頻範圍為1.5至10.2 GHz(137.2%)。最後，設計二個注入鎖定除六除頻器，使用台積電0.18 μm BiCMOS製程，第一個除頻器使用一個低頻除二ILFD疊接一個高頻除三ILFD達到除六的效果,此ILFD在輸入0dBm時,除六的鎖頻範圍為8.4GHz至13.8GH(48.6%),而第二顆除頻器使用 CML (current-mode logic) 除二除頻器疊接使用電容交叉耦合式之除三注入鎖定除頻器所構成；CML 則為

在 flip-flop 啟用上緣 clock 輸出切換 到輸入，以致於輸出頻率為輸入的一半；且負載較為小，則有較小的 RC 延遲， 但需要提高電壓來補償下降的迴路增益，做為功耗與延遲之 tradeoff。因此使用 CML 疊接 ILFD，讓直流和交流電流可以更有效使用，此ILFD在輸入0dBm時，除六的鎖頻範圍為 8.5GHz至 10.9GHz(24.7%)

Database Systems: A Pragmatic Approach, 3rd Edition

為了解決Phoenix RC的問題，作者Foster, Elvis C. 這樣論述：

Database Systems: A Methodical Approach, 3rd Edition provides a concise but comprehensive guide to the disciplines of database design, construction, implementation, and management. Based on the authors’ professional experience in the software engineering and IT industries before making a career swit

ch to academia, the text stresses database design skills to properly design and develop software applications. The discipline of database systems design and management is discussed within the context of the bigger picture of software engineering. Students are led to understand from the outset of the

text that a database is a critical component of a software system, and that proper database design and management is integral to the success of a software system. Additionally, students are led to appreciate the huge value of a properly designed database to the success of a business enterprise. The

text was written for three target audiences. It is suited for undergraduate students of computer science and related disciplines who are pursuing a course in database systems; graduate students who are pursuing an introductory course to database; and practicing software engineers and information te

chnology (IT) professionals who need a quick reference on database design. Features of the third edition include: Short paragraphs that express the salient aspects of each subjectDiscussion of DBMS alternatives such as the Entity-Attributes-Value model, NoSQL databases, database-supporting framework

s, and other burgeoning database technologiesBullet points itemizing important points for easy memorization Fully revised and updated diagrams and figures to illustrate concepts to enhance the student’s understandingReal-world examplesOriginal methodologies applicable to database design Step-by-step

, student-friendly guidelines for solving generic database systems problemsOpening chapter overviews and concluding chapter summariesA chapter with sample assignment questions and case studies Elvis C. Foster is a Professor of Computer Science at Keene State College. He holds a Bachelor of Science

使用網路對於老年人自覺性健康之影響

為了解決Phoenix RC的問題，作者賴奕辰 這樣論述：

二十世紀末的資訊革命後，資訊網路普及和科技的進步為人類帶來更便利的生活以及更完善的醫療環境，使得人類壽命更加延長，卻也因此讓老年族群健康以及照護問題成為一大隱憂。然而在過去的研究中，資訊網路的使用常被認為可以解決老年族群的心理健康問題，像是網路使用降低憂鬱程度或使用網路社群可以降低老年族群的孤立感等，較少有資訊網路帶來之負面影響的相關研究，然而近年來出現越來越多因資訊網絡的普及出現的負面影響，如科技冷漠、數位落差以及數位焦慮等，因此各國也開始對於資訊網路可能所帶來的負面影響進行研究。儘管如此，有關資訊網路的討論，依舊大多針對網路使用對其心理健康的影響，且探討的族群通常較為廣闊，較少有針對其網

路使用對其生理健康影響以及特定族群使用網路影響的研究，因此本研究將特別針對台灣60歲以上的老年族群，分析網路使用對其自覺性健康的影響，了解網路使用對於台灣老年族群自覺性健康的影響。本研究利用行政院國家發展委員會「2018年資深公民數位機會調查」之調查資料，本研究使用熟識好友是否使用網路作為工具變數，配合IV-Probit model分析，以降低內生性所造成的估計誤差。實證結果顯示，台灣老年人若有使用網路，對於其自覺性為健康的機率將會上升67.3%。此外在性別為「女性」、「較低的教育程度」、「目前無工作」、「年齡介於65-80歲」以及「主要從事室外類型活動」的族群影響效果更加顯著。
