What is the problem with the design of the bandgap with nA?

[asicpark]

Hi all,

I'm trying to design the bandgap circuit.
but it is used for the low power application, so it is allowed to consume
only the hundreds of nano amphere.

I'm not sure what the problem and difficulties in that case.
Could you share your exprience with me?

Thanks,

from power supply noise rejection prespective, it may be susceptible to noise at higher frequencies.
