Abstract :
This paper presents a low power, high resolution 2.4 GHz CMOS frequency synthesizer for low power wireless LAN applications. The PLL frequency synthesizer consists of a fully programmable frequency divider with a resolution of 1 MHz in the range of 2.4 GHz-2.484 GHz.The measured results showed that the programmable divider consumes 946 uA and Quadrature VCO consumes 1.57 mA and produces output swing of 650-700 mVpp. The complete synthesizer is designed using the Chartered RF 0.18 um process and synthesizer consumes 2.7 mA.
