I have to design a buffer which buffers 0.6V voltage (which is coming from Bandgap ...) to some other block.

Any noise/ sudden variation at the output should not affect the input of the buffer. what do I need to consider in my design (not layout), to make sure that this noise doesnt reflect at the input?

Thanks
 

Buffer TL081 . Tie output to neg input . use pos input for signal and output for output.
Typ it will have Hi Z in And LoZ out good isolation and dont forget the decoupling caps on the amps pwr legs to ground.
