dc.description.abstract | 本論文分為兩部份,第一部份利用0.18微米互補性金屬氧化物半導體(CMOS)製程,提出了一個10.5 GHz 微波混頻器 (MICROMIXER) 應用在 X頻段的調頻連續波(FMCW)雷達系統。在電路方面,為了提升混頻器在整個系統的隔離度(isolation),並免干擾其他電路的功能,電路設計與佈局技術特別注重此特性。在被動元件方面,傳輸線型式之電感與由介質基板及上、下兩層互補式金屬圖案所構成合成傳輸線(CCS TL)結合運用在此混頻器。另外,降頻混波器的設計與特性也有詳細的討論。
本論文的第二部份提出一個10.5 GHz介質諧振振盪器 (Dielectric Resonator Oscillator) 結合了單晶片微波積體電路(MMIC)利用0.18微米互補性金屬氧化物半導體製程。圓形的微帶線取代了原本的直線的微帶線,圓形的微帶線與介電共振器(DR)耦合提供較高的負載品質因數(loaded Q),其相位雜訊在100 kHz位移為 -118 dBc/Hz。為了達到較低的相位雜訊,場論方析用來最佳化介質諧振振盪器的耦合電路。 | zh_TW |
dc.description.abstract | In this thesis, firstly, a MICROMIXER for X-band FMCW radar application is realized in 0.18μm CMOS process. At circuit level, circuit and layout technique to improve the isolation are discussed. At device level, the synthetic guiding structure complementary-conducting-strips (CCS) transmission line and transmission line inductor are employed to the mixer. In addition, the design and characterization of downconversion mixer are described.
Secondly, an X-band dielectric resonator oscillator using MMIC fabricated by 0.18μm CMOS process is presented. The novel circular line DRO used to replace the conventional straight line DRO features higher loaded Q. This circuit demonstrated a low noise of -118dBc/Hz at offset frequency of 100 KHz. Field analysis help in finding optimized DR coupling circuit that DR would be coupled to achieve better phase noise. | en |
