此論文提出了一個壓控振盪器和二個注入鎖定除頻器,它們分別使用了標準台積電0.18微米和0.35微米CMOS製程去實現。
在壓控振盪器裡,此振盪器包含兩個由pmos為中心所組成的考畢子壓控振盪器單端VCO以串連形式堆疊而成,量測結果顯示其在其輸出之相位雜訊在頻率5.52 GHz其1 MHz處所量測之結果為-114.89 dBc/Hz,而其消耗功率在供應電壓1.6 V之下只有7.26 mW,其調變頻率則可從 5.15 GHz 到 5.85 GHz。
在注入鎖定除頻器(ILFDs)中,第一個注入鎖定除頻器是開關式電感雙頻帶注入鎖定除頻器,藉著開關電感的開關,可以達到雙頻帶除頻器。其鎖定範圍在低頻帶和高頻帶分別是從4.0 GHz 到 5.8 GHz 和 從 8.48 GHz 到 9.3 GHz。第二個注入鎖定除頻器是互補式哈特萊注入鎖定除頻器,量測結果顯示其所鎖定範圍在注入功率0 dBm之下為14.94~16.05 GHz。


This thesis presents one voltage controlled oscillator and two injection locked frequency dividers, which are implemented by using standard TSMC 0.18um and 0.35um CMOS process respectively.
In voltage controlled oscillators, the oscillator contains two single ended VCO’s with two pMOS-core Colpitts oscillators stacked in series . The measurement shows the phase noise of -114.89 dBc/Hz at 1-MHz offset from the frequency 5.52 GHz while dissipating only 7.26 mW for the core VCO from the supply voltage of 1.6V. The tuning range of VCO is tunable from 5.15 GHz to 5.85 GHz.
In injection locked frequency dividers (ILFDs), the first injection locked frequency divider is a switched-inductor dual-band ILFD. By switching on/off the inductor switch, a dual-band frequency divider can be obtained. The locking ranges of low-frequency and high-frequency band are respectively from 4.0 GHz to 5.8 GHz and from 8.48 GHz to 9.3 GHz. The second injection locked frequency divider is a complementary Hartley ILFD. The measurement shows the locking range is from 14.94~16.05 GHz when the injection input power is 0 dBm.
