Abstract
This paper presents low phase noise, precise frequency tuning range LC Voltage controlled Oscillator (VCO) circuit of Phase lock loop, to support - IEEE 802.11a/b/g, Bluetooth, Zigbee and IEEE 802.15.4., operating on 2.4GHz ISM band (Industrial, Scientific, Medical). The presented circuit is implemented in Cadence virtuoso environment and using GPDK090 Library of 90nm CMOS Technology. The presented VCO is tuned at 2.4GHz frequency with tuning range of 80MHz. The measured Phase noise is -126.3dBc/Hz at 1MHz offset frequency. The total power consumption of the presented VCO is 4.7mw at 1V power supply.Keywords
