Abstract :
Low phase noise characteristic can be in a VCO (Voltage Controlled Oscillator) by using a high Q SAW (Surface Acoustic Wave) device. In this type of VCO, new method for obtaining both wide tuning range and low phase noise characteristic is proposed and experimentally verified. This paper also shows the feasibility of single chip VCOs using PLIC (Poly-Lithic Integrated Circuit) technology compatible with CMOS integrated circuit technology, which allows us to develop a true single chip mobile communication system.
