I have designed a decimation filter for Delta Sigma ADC and now I want to calculate the SNR of Delta Sigma ADC after the modulator and then after Decimation. As far as Schrier and Malcovati's Toolboxes are concerned I was unable to apply them (How to use them because lot of parameters to be mentioned ? :|) to decimated data so any helpful tutorial/suggestion related to problem will be highly appreciated.
I hve also designed a delta sigma ADC and i calculate the SNR .In order to caculate the SNR after the modulator you must make the fast fourier transform function (FFT) by MATLAB after the modulator.
About the decimation,until now i have designed the complete ADC in Smulink (MATLAB) then by using CADENCE, i only designed the modulator with layout.
My problem is how to design this filter with layout.
