nutralization of a DCE stage

[kaitlyn]

a nutralized DCE-stage can yield high out-to-input isolation.
1,high out-to-input isolation means the network just like unilateral, am I right?
2,and what's the principle of this structure?
3,how the cross connected capacitances eliminate teh effect of Cbc of the differential input transistors

I'm a new guy in this field, please help me

Hey new guy, I'll bite, what's a DCE?

 

[kaitlyn]

this nutralization of DCE is differential common-emitter stage by employing bridge neuralization.

Thanks a lot!
