Title: SFDR analysis Post by richloo on Feb 7th, 2005, 6:13pm hi guyz, can anyone tell me wat is SpuriousFreeDynamicRange and how to simulate it??? I was told this is an important parameter for CT filter. Thanks in advance! |
Title: Re: SFDR analysis Post by venkat on Apr 29th, 2005, 4:48pm SFDR is the difference between the first (fundamental) frequency peak and the next highest harmonic peak in a fourier plot. It gives an indication of how good is your rejection in terms of the baseband signal |
Title: Re: SFDR analysis Post by venkat on Apr 29th, 2005, 4:51pm To simulate it, simply plot the FFT of the AC responce and write the diff equation in the calculator in cadence. (Be careful on noting the peak ... it might be in Volts or power... appropriately take the difference) |
