What's a current feedback amplifier?

Another opamp question. Most opamps seem to be voltage feedback amplifiers (VFA), but there also seem to be current feedback amplifiers (CFA). When would you use a CFA, and what are their (dis/)advantages?

Current feedback OPAMP analysis

Till now I studied voltage feedback opamps and I know how circuits involving them are solved. What is difference between current feedback and voltage feedback amplifier? What are steps in analysis of current feedback opamps?

Why do current-feedback amplifiers have a higher bandwidth?

The advice when dealing with amplifying high-frequency signals always seems to be "use a current-feedback amplifier, not an op amp". (see 1, comments on 2, 3 and comments on its question) But why is this? What about current-feedback amplifiers makes…

Can any one explain the Proprietary Offset Circuit block diagram in this circuit AD8211?

In this circuit a Proprietary Offset Block diagram is used, in practical at 5mV lower Differential voltage output is 100mv as expected. But Getting almost 150-200 mV in different temperatures and corners. Can anyone explain this ?
