When checking the SNR/ENOB of a 10bit ADC circuit, do we need to get as least 1024 sample points? so 4096 for12bit ADC.4 \( i* w2 J" N* w* {5 Y: C
6 m$ d& r+ g8 ?; QIn other words, when simulating a 10bit ADC, we have to run a transient analysis with more than 1024*(1/fs) time period. ) S, ~7 p% Y! [1 K; H5 v8 ^6 Y) r p7 O4 w9 s+ I; Q
Please give your inputs here. Thanks a lot in advance!作者: iamif520 時間: 2009-11-18 02:35 AM
I will give at least 1024*10*Ts
