Some places mention an ideal transistor is unilateral. But is that the case in reality?
For example for a BJT we say that the base current or Vbe controls the output port such as emitter current or Vce not the otherway around. I guess this is what they call unilateral.
But in a common emitter amplifier if we change the load between Vcc and the collector wouldnt the base current change? Isnt that behaviour bilateral?
And is Early Effect is an example of bilateral behaviour?
