Could someone explain why a self biasing JFET amp (for example:
http://www.mission-technology.com/ELECLABS/images\21lb10_1.gif) would
display the miller effect? There isn't any feedback, so there
shouldn't be any miller effect.. right?

In Erno Boberly's great article "JFETS: The New Frontier Part I"
(http://www.tkhifi.com/div/Erno_Borbely_fet_articel_1.pdf).. he
mentions how the JFET amp can have this huge input capacitance with a
large gain. But.. these amps don't have feedback... so why?
Thanks
