How do i decide how much current i should pass through the rail and cascode devices and how much through the nmos i/p diff pair(to tail current source) in afodled cascode config?
for eg: I want 100u passing through the tail source so i decide say 80:flows through to the folding node on the rail and cascode side(pmos side) and 30u to flow through the nmos side...is this fine?..min power dissipation spec is 0.75mW and 2.7v supply.I need a ugf of 5Mhz with a 5pf load..
