WebSep 7, 2024 · A PNP Bipolar Junction Transistor has an N-doped semiconductor base in between a P-doped emitter and P-doped collector region. The PNP Transistor has very similar characteristics to the NPN Transistor, with the difference being the biasing of the current and voltage directions are reversed. WebUnlike the common-emitter circuit, the input and output signals in the common-base circuit are in phase. To illustrate this point, assume the input to the PNP version of the common-base circuit in figure above (view B) is positive. The signal adds to the forward bias, since it is applied to the emitter, causing the collector current to increase.
