I have designed a 2nd order delta sigma modulator. In TT 25 corner the SNR is 63.8 dB. The worst result is obtained in the SF 85 which has 33 dB SNR. I want to improve the modulator performance so that it reaches a minimum SNR of 62 dB in all corners.
Is it possible to do this by improving the opamps, that is increasing their gain or bandwidth, or should I do something else?
Any suggestion.
