Can anyone tell me why does my op amp goes into oscillations when I increae the bias volyage..I have decoupled the supply with 3 sets of capacitances on each side..still it just puffs up...
by increasing the bias current i think you are lowering the output resistance seen by the output capacitor and hence the phase shift is increasing due to the RC value....

I gave an external power supply to the op amp (..with constant current) what dont understand is if the oscillations are due to any ground effects at the input or due to decoupling faults..
