A good place for the rarely-used cascode stage.Hate to correct you, but a cascode amp consists of TWO transistors. (Or vacuum tubes, back when it was invented :)) It helps fight the Miller effect making it easier to get high bandwidth.
Kind of an interesting way of building a tetrode out of two triodes...
Way off-topic, but the DUAL GATE FETs could be viewed as a single transistor cascode amp.
Thanks for the correction! I overlooked the second common-base transistor. Sorry for the distraction. ;-) -michael NadaPong: Network game demo for Apple II computers! Home page: http://members.aol.com/MJMahon/ "The wastebasket is our most important design tool--and it's seriously underused."
