Hi, guys. If you need to design a high speed high precision op-amp, what architecture will you choose, and how to make the trade off?

This question is bothering me, thanks for answering.

The simplest the fastest.
Burn more current, use just one stage.

The term high precision can mean lots of things.

Are you asking for a 100MPG Maserati?

High precision (or accuracy) tends to want elaborate
error cancelling circuits at the front end. That baggage
is not your friend if you want bandwidth.

What are your accuracy "values"? Do you just want
a minimal Vio? Can you stand having chop-tones, to
get it? Bias current, bias current flatness w/ temp
and aging? Noise matter to you?

There are a zillion op amps in catalogs because no
single perfect (non)-compromise exists.
