Title: Re: how to simulate the stability of LDO(connected Post by sheldon on May 9th, 2007, 5:25am Wave, Never tried this configuration before, but SpectreRF periodic stability analysis should be able to calculate the stability characteristics of the circuit. To use, 1) Calculate the periodic operating point, that is, run autonomous PSS 2) Run Periodic stability analysis, pstab In the past, I have used this analysis to calculate the gain and phase margin of dynamic circuits, for example, DC-to-DC Converters and VCOs. You just need to make that you correctly define the loop. Best Regards, Sheldon |
