PNP transistor (structure, operation, models)

PNP transistor (structure, operation, models). Reading: Chapter 4.6. PNP Transistor. The operating principle of a PNP BJT is the same as that of an NPN BJT. Note that the bias-voltage polarities are reversed for the PNP device, compared to an NPN device.

BIPOLAR JUNCTION TRANSISTORS (BJTs)

BIPOLAR JUNCTION TRANSISTORS (BJTs). have considered the junction diode - basic 2-terminal device now consider the 3-terminal device - much more useful 3-terminal device: use voltage between 2 terminals so as to control the current in the 3rd terminal. 3-terminal devices .
