Abstract :
This frequency synthesizer presents a fully integrated solution by using a newly developed low noise, wide bandwidth ring-based VCO which depends on inductive peaking. The new VCO is characterized by its low phase noise and power consumption compared to ordinary ring VCO while keeping all of its advantages like small size and high integration capability. The frequency synthesizer is implemented on a standard 0.13mum technology and achieves a phase noise performance of -120dBc/Hz at 3MHz offset. The output frequency of the synthesizer covers the 2.4GHz ISM band with a resolution of 1MHz consuming 12.5mA from a 3.3V supply and a total chip area of 0.05mm2.
