Parametric Amplifiers

Hello !

I am looking for information on parametric amplifiers ..

Any books, thesis or papers would help !

Anyone in this field would help too

thanks

Nowadays with the very low noise FETs practically no reason to use parametric amplifiers.
If you must know about them for some other reasons go to Google, write in "Parametric amplifier" and you will get a lot of results to start on.
