In this thesis, there are two types of varactors used in the VCO: one is the Philips' BB135 p-n junction capacitor; the other is Al/HfO2/Si capacitor with HfO2 dielectric. Because the dielectric constant of HfO2 is larger than that of SiO2, the capacitance of Al/HfO2/Si capacitor will be larger than that of MOS capacitor with the same thickness and area. Therefore, there will be larger unit voltage for adjusting the ratio of the capacitance values of the capacitors.

在本论文实验的VCO电路中之可变电容有2种：一种是飞利浦厂商所提供型号为BB135之P-N接面电容；第二种是自制的Al/HfO2/Si电容是使用二氧化铪（HfO2）来做为电容的介电材料，因为HfO2介电常数比氧化矽（SiO2）大，目的是要在相同厚度以及面积下，就可以有较大的电容值，希望能藉此有较大的单位电压改变电容值的比值。
