hi, the opa of your bg may get 100db by increase output risistance. i care the stable loop. Can you give me the result about positive & negtive bode sweep?
hi, as i know, the offset of vth is 10mv or so in common conditions. i concerned if reduce the vgs-vth and make input pair saturate easy, but Delt(vth)/(vgs-vth) seems more sensitive and bring new 'offset'
it's my self option, i wonder the truth..Hah

in fact, you can add extra two resistors connected the vdd and vgnd respectively to limit the current. the tech is applied in actual ICs.
wish it can help u.
