Analog devices AD4899-1 voltage noise = 2nV/rtHz @ 10Hz; GBW = 300MHz.

The voltage noise is only 7 nV/rtHz @ 100 Hz (gain=2, I'll be using g=1), which is the best I've seen so far for a wideband amp.  Not as good as the discrete transistor circuit, but it would use alot fewer parts.  It only needs to be better than a 'good' OCXO.
