| dc.description.abstract | 本論文提出操作於Ka頻帶之互補式差動振盪器與四相位壓控振盪器，以應用於未來第五代行動通訊。
第一個電路使用LC共振腔產生振盪訊號，並以兩組交叉耦合對提供負轉導，達到同時降低振盪門檻與功率消耗的目的。電路採用台積電90nm CMOS製程實現，而量測結果諧振頻率由29.3GHz變化至34.6GHz，距離中心頻率1MHz之相位雜訊介於-85.9dBc/Hz與 -99.1dBc/Hz之間，輸出功率為-2dBm，直流功耗最大為16.7mW。第二個電路採用同樣方式振盪，而負轉導產生方式改以電流再利用技術實現，以降低直流功耗，並將兩組振盪器以電晶體耦合的方式產生正交訊號。電路採用台積電180nm CMOS製程實現，而量測結果諧調頻率由29.8GHz至28.3GHz，距離中心頻率1MHz之相位雜訊介於-86.6dBc/Hz與-103.2dBc/Hz之間，輸出功率為-11.3dBm，直流功耗低於35mW，相位誤差最大為9°。 | zh_TW |
| dc.description.abstract | This thesis presents two VCOs using CMOS process for upcoming 5G wireless communication system.
The first oscillator generates sinusoidal signal by LC tank with varactors and uses two cross-coupled pairs to produce negative conductance such that stable oscillation can occur and power dissipation can be reduced. Measurement results show that the signal can be tuned from 29.3 to 34.6 GHz with 16.6% tuning range and the measured signal output power is above -2dBm. The core consumes 8 mA and two buffers consume 6mA in total from 1.2 V power supply. The measured phase noise at 1MHz offset varies from -85.9 to -99.1 dBc/Hz. The second oscillator combines two identical VCOs with current-reused technique to generate negative conductance. Additional transistors are used to couple between two differential VCOs to generate quadrature signals. The measured tuning range is from 29.8 to 28.3 GHz and the maximum phase error is 9°. The measured phase noise at 1-MHz offset is among -86.6 to-103.2 dBc/Hz with a total of 20mA DC current from 1.8-V supply. | en |
