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.
