    ADC with 12 bits output

    Hi,

    Some question regarding digital low pass filter for ADC.
    If I need 12 ENOB output do I have to implement dcimation filter (CIC) with decimation factor at least 4096? And ENOB and stable output bits are the sam

    Re: ADC with 12 bits output

    Most likely much lower, depends on the modulator characteristic and it's output spectrum. Refer to basic SD ADC literature.

    I'm not aware of clear definition of stable output bits.
