That idea has been round since about the 1920s, and keeps getting reinvented. A much better method is to use capacitive feedback and fix up the frequency response in the second stage.

Oops - sorry for linking to that nonsense, I didn't notice that the article was 10 years old (EDN sent me a link to it today for some reason). EDN used to be a good read back in the 80's.

"When men were men, women were women, and small furry creatures from Alpha Centauri were real small furry creatures from Alpha Centauri." I used to like Circuit Cellar too, when Steve Ciarcia was running it. Cheers Phil Hobbs

Yes. I was a long time subscriber. Then Steve sold out and the price about doubled. I dropped it then.

I never bought into CC - it always seemed to be 101 variations of the same circuit. In fact I never thought much of any of the US magazines. IMHO Wireless World topped them all (at least until the late 80's) http://www.americanradiohistory.com/Wireless_World_Magazine.htm.

I liked " Ham Radio ", but it was bought out by CQ and that was the end of that. Dan
