本論文主要分成二個主題:第一個部份是VCO的原理架構與設計要領;第二個部份是除頻器的原理與LC Tank Divider及Quadrature ILFD的晶片設計實作與量測。我們分別使用是TSMC0.18 µm CMOS 1P6M及TSMC 0.35 µm CMOS 2P4M製程,且利用Spectre RF及ADS軟體來進行電路模擬。未來目標希望能整合振盪器與除頻器的概念,將除頻器可使用於PLL之中,使其能操作在2.4GHz或更高頻的應用


This thesis is mainly composed of two topics. The first is the fundamental of the VCO theory and the design key. The second is that theory of Injection Lock Frequency Divider and the chips of LC Tank ILFD and Quadrature ILFD are designed, achieved and measured. Two chips are fabricated by TSMC 0.18 µm CMOS 1P6M and TSMC 0.35 µm CMOS 2P4M processes, we use Spectre RF and ADS to simulate circuits. In our future work, we want to integrate the concepts of the oscillator and divider, use the signal of divider in the PLL, enable it to operate it in 2.4 GHz or application of high frequency.
