DC Long Tailed Phase Inverter

This is typically a vacuum tube phase inverter topology, but the same principles apply to transistors. How it works, well one bias chain is AC grounded, and the other part of the topology works in a normal common emitter mode. When the common emitter circuit raises the output voltage, the current on the emitter constant current source falls. By falling it allows the other stage's current to rise by exactly the same value, thus inverting thr output. Perfect symmetry is obtained when both stages are connected to a constant current source.

Its called differential amplifier or OpAmp - is this the little school you have been? http://imgur.com/CyXw4Wy

Yes i know it's an op amp thank you haha. I'm just implying that I've taken this topology from a tube phase inverter.

No, that's not a school i think. I've went to PGAVT ,,A.S. Popov''
