Phase noise degradation of LC-tank VCOs due to substrate noise and package coupling

The present work addresses the investigation of phase noise degradation of LC-tank VCOs due to realistic digitally originated substrate noise. The dominant mechanisms by which this noise is coupled to the output of the oscillator due to the substrate and the package are analyzed, indicating that bot...

Description
Summary:The present work addresses the investigation of phase noise degradation of LC-tank VCOs due to realistic digitally originated substrate noise. The dominant mechanisms by which this noise is coupled to the output of the oscillator due to the substrate and the package are analyzed, indicating that both noise at low frequencies and at high frequencies around the oscillation fundamental significantly degrade phase noise.
