Figure 0.9, Constant Voltage Biasing Circuit with a Thevenin's equivalent circuit replacing the voltage divider in the base circuit. There is a battery on the left labeled V sub BB. The negative end connects to common. The positive end goes to one end of a resistor labeled R sub B. The other end of R sub B goes to the base of an NPN transistor. There is a battery on the right labeled V sub CC. The negative end is connected to common. The positive end goes to one end of a resistor, labeled R sub C. The other end of R sub C goes to the collector of the transistor. The emitter of the transistor goes to one end of R sub E. The other end of R sub E goes to common. This completes the verbal description.
