I do not think that the output resistance is really the limiting effect here, but rather the speed at which the transistor reacts, ie its f_t. But I have to admit that I have not fully understood the circuits behaviour yet. I still lack good understanding of how a transistor behaves under high frequency conditions :-/ Attila Kinali -- Malek's Law: Any simple idea will be worded in the most complicated way. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
