A varactor model including valanche noise source for VCOs phase noise simulation
, 2011 — This work studies an important area of oscillator operation – VCO biased at varactor breakdown. In this operation, the oscillator’s phase noise is primarily determined by avalanche noise generated in the varactor, i.e., the phase noise can be modulated
