Hi~~
i have a question :
often say the first OTA of sigma delta modulator will dominate the noise ,it thermal & flicker noise
if i have a three stage modulator ,the ota1 has fllicker noise at -100dB and ota2&3 have -80dB
Is the modulator's low frequency would be -100dB only dominate by ota1 ?
thanks~~~
