I don't get why the collector base junction is put in reverse bias or how that even helps. It seems to be the same as a common base transistor. (where the emittor base junction is in forward bias and the collector base junction is in reverse bias).The diagram is equally confusing. I just don't see the difference.edit: Could somebody please check the following diagrams and point out errors, if any?
