Modelling noise in Power supply

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.
