Abstract :
The paper presents a low power and low phase noise voltage controlled oscillator (VCO) for IEEE 802.11a applications. The quality enhancement and reducing current architecture is designed to improve phase noise and power. The measured results exhibited phase noise -115.62 dBc/Hz at 1MHz offset frequency and measured tuning range is about 14.5% from 5.26GHz to 6.08GHz. The power dissipation is 2.26mW and FOM is -187dBc/Hz. The chip fabrication of VCO is made by TSMC 0.18μm 1P6M CMOS standard process.
