Transistors

Transistors

1. The emitter current of a transistor is the sum of its base and collector currents.

2. The common emitter current gain of a transistor is the ratio of collector current to base current and is typically in the range 40 to 200

3. Integrated circuits contain large numbers of individ- ual components fabricated on a single slice of sili- con.

4. Integrated circuits are often classified as either digital (logic) or linear (analogue).

5. operational amplifiers are linear integrated circuits that can be used as versatile gain blocks' within a wide variety of linear circuits.
