Abstract :
A fully integrated wide tuning range and low power VCO, using a new combination of accumulation-mode (A-MOS) varactors in LC tank, has been presented. The VCO is implemented in 0.25-mum technology and has a tuning range of 1.35GHz, from 4.93GHz to 6.28GHz. It consumes 1.8mA of current from a 2.5V supply and achieves low phase noise of -116.1dBc/Hz @1MHz offset from 5.7GHz carrier. The VCO designed has a tuning range, which covers all of the three bands of IEEE WLAN 802.11a standard and satisfies the phase noise specifications
