I am designing a OTA used in the residue amplifier of a pipeline ADC,
but i do not know the requirement the the OTA specially the slewing rate and GBW.
Who can tell me the requirement of slewing rate and GBW
Thanks!
Single stage assume,GBW>{[2F(N+1)Ln2]/(2Π)}*(1/f).
Where F is sample frequence, N is resolution. f is feedback factor.
you should better read some paper about Pipeline.
