PLL Random Jitter Estimation Using Different VCO Phase Noise Simulation Methodologies
Random jitter (RJ) is a significant noise component in PLL systems that use ring-based oscillators. In order to estimate RJ, accurate modeling of the VCO phase noise is essential. In this paper, the authors will present how the VCO phase noise they obtained from HSPICE RF and from the Impulse-Sensitivity Function (ISF) method compared to lab measurements, the limitations of the two methods and ...
متن کاملNonlinear Distortion Model for VCO-PLL FM Transmission Systems
The nonlinear distortion of frequency or phase modulation systems composed by a voltage-controlled oscillator (VCO) modulator and a phase-locked loop (PLL) discriminator is addressed. Volterra series nonlinear transfer functions up to third order, for an LC Colpitts type modulator and a PLL with simultaneous nonlinear phase-detector and VCO, are combined as a cascade of mildly nonlinear systems...

متن کاملVCO Jitter Simulation and Its Comparison With Measurement
We have simulated the phase noise of a voltage controlled oscillator (VCO) using an RF circuit simulator, SpectreRF [1]. This simulator uses a variation of the periodic noise analysis rst proposed by Okumura, et al [2]. It computes the power spectral density of the noise as a function of frequency. By assuming that only white noise sources are present in the oscillator it is possible to derive ...
