In this document: Virtuoso Spectre Transient Noise Analysis
The PN() function is used to calculate the phase noise after transient simulation with this equation: (p.55)

What's the reason for the last term: dB20(twoPi*f0_pss), i.e. dividing the power by 2*pi*Fc ?
I'm confused how the PN() function implements the calculation of phase noise as defined in the same document: (p.53)

Does it automatically normalized the jitter power to signal power as the equation in this another document: Jee Measurement using PSS/Pnoise and Transient Noise Analysis? (p.33)
