An N-Stage series Transistor Circuit

A description is given of some of the characteristics of a circuit wherein a number of transistors are connected so that the sum of their collector to emitter voltages appears across a common load. This circuit permits large output voltage swings to be obtained and provides a means for adding the power outputs of a number of traits. The circuit is analyzed as a cascade of common base stages with added base resistors. The contribution of the individual stages to thc total output is determined by the manner in which the base resistances are selected. Three cases are treated: equal division of voltage, equal power increase per stage, and equal power output per transistor.
