tripple cascode

i am trying to design a triple cascode (telescopy) OTA, but I don't know how to generate the BIASing structure of this HIGH SWING OTA.

thx
 

self biasing of ota

I didn't get ur question. But if u r asking about the biasing voltages, so in real IC's these voltages are generated from the bias cells, like the bandgap reference.

please clarify ur question
 

biasing a cascode structure

I think you may need self biasing using resistors but if u need high swing try the folded cascode
try to check anaolg design book like razavior meyer
 

telescope bias

use the high swing configuration to eliminate the Vt from the swing range. check out meyer's.
