Abstract :
A monolithic LC oscillator design is presented with a carrier to noise ratio (CNR) of 118 dBc/Hz at 2 MHz offset of the 1.3 GHz carrier. Circuit optimization is performed utilizing a novel phase noise simulation method. The described method uses standard AC noise simulation resulting in fast phase noise simulations with simulation times in the order of 30 to 60 seconds. The LC oscillator design is implemented in an advanced bipolar Silicon On Anything (SOA) process. This technology features extremely low parasitics and high quality coils and varactors. The SOA process has enabled a low power VCO design dissipating only 0.8 mW. Measured tuning range is 1.15 GHz to 1.3 GHz
