Effective Number of Bits<br />

An ideal ADC suffers only from quantization noise<br />

SNR <br />

SQNR 6. 02dB<br />

N 1.<br />

76dB<br />

Actual ADCs have lots of impairments (noise, nonlinearity)<br />

that limit the effective resolution.<br />

Effective number of Bits:<br />

ENOB<br />

SNDR<br />

6.<br />

02<br />

1.<br />

76<br />

dB<br />

Note: The number of bits coming out of an ADC doesn‘t say<br />

anything about the actual resolution<br />
