Re: i need a comment
Hello,
I am designing a low pass Gaussian filter with fc=1920Hz. I obtain this frequency but the phase margin forever is false.
The following pictures show the ideal response and the obtained one of this filter:
Can any person help me in this case and tell me how to modify the phase of this filter?
Best regards.

Now, i make an ideal simulation on Cadence using a filter butterworth_lp from rfLib. I obtain the following results.
Can any person tell me that the simulation results of my filter are true or false?
Best regards
