WebBJT which is not practical. In a simple biasing circuit, V BB is eliminated by connecting the resistor R B to the supply V CC. This biasing circuit is called base bias, or fixed bias, see Figure 5.6 (b). (a) (b) Figure 5.6 An npn transistor with base bias.

The collector is moderately doped and the emitter is heavily doped. • The base region is much thinner than the either the collector or emitter regions. Typical base widths are about 10-6 m. • The collector region is usually thicker than the emitter as the largest how do you score through text in excel
