. This jitter is accumulating jitter. This application note illustrates how to use the Spectre and SpectreRF simulators within the Analog Design Environment ADE to measure jitter characteristics of the PLL circuits. 64 Cadence - SpectreRF Workshop - 2015 - VCO Design Using SpectreRFpdf 201 MB 下载次数.

For each block the phase noise is extracted. The current consumption of the ring oscillator is more or less proportional to frequency and thus can be used as a plot of frequency versus voltage. VCO have only cycle-to-cycle jitter as the jitter performance as mentioned below For autonomous circuits where there are no ideal reference transitions you are limited to using self-referred jitter metrics.
