Transistor Operation

Transistor Operation: pnp and npn Transistor Operation – A junction transistor is simply a sandwich of one type of semiconductor material (p-type or n-type) between two layers of the opposite type. A block representation of a layer of p-type material between two layers of n-type is shown in Fig. 4-1(a). This is described as an npn …
