Hi all, happy new year!

I have my first question this year. I am trying to understand how a common-base BJT LNA works. The circuit I am analysing uses a transformer feedback.

Does anyone know any literature, web site, articles about this type of amplifiers?

Does anyone know what are the advantages of using this transformer feedback?

Best regards.
 
A common base configuration eliminates the Miller effect, so they work well in wideband applications.

Microelectronic Circuits by Sedra and Smith gives a good introduction to the common base configuration.
