low noise bandgap

Is it possible to design a very low noise bandgap reference?
(without using any RC filter).

Will it help using a chopper?

say 20-30uV rms in 10hz to 100kHz.

thanks in advance.

Even the dedicated analog semi companies hardly can achieve this
S. e.g. **broken link removed**.

Thaks eriki,

i have gone thru this datasheet.
but the current consumption is very high....prohibitively high...

regards,
