On the other hand, a pnp transistor is formed by introducing a thin region of ntype material between two regions of ptype material. Of course, as the charge carriers move toward the junction and disappear, they are replaced at the ends by charges moving into and out of the wires.

Next we will talk about diodes, followed by the bipolar junction transistor. Transistors can also be used as switches but since this is not a course in digital electronics, we will not discuss the function of transistors. The input signal of small amplitude is applied at the base to get the magnified output signal at the collector. Then you learned how circuit elements do not operate the same at all frequencies. In the pnp transistor these polarities are reversed. Fourlayer devices act as either open or closed switches.
