Modelling noise in Power supply

Jithin

Hi,

I'm designing a VCO based on ring oscillator architecture and would like to simulate power supply Jitter using cadence spectre. so please help me in adding noise to power supply or help me in modelling supply with jitter.

Thanks in advance.

with regards,

Jithin

    Hi Jithin

    Perhaps you might want to try spectre's transient noise function which is useful for modelling a noisy power supply.


    Best regards

    Also look in your MMSIM installation, under <MMSIMinstDir>/ tools/spectre/examples/SpectreRF_workshop/PSRR_Osc_AN.pdf for methods to do this more efficiently using the SpectreRF analyses.

    Regards,

    Andrew.
