I need help to decide the tail current for telescopic amp

[butterflymadu]

hye..

i need some help to deciding the tail current M9...

if my output swing at node X
= 1.25

what is the posibble Vod9 so that all the transistor will be in saturation..(need to get for the initial calculation..)

Vod7+v0d5+vod3+vod1+vod9 = 1.25V
