The known parameters in Figure 425 are = 100, V =0:7V, RC =1 k, and VCC

The known parameters in Figure 4–25 are β = 100, Vγ =0:7V, RC =1 kΩ, and VCC = 5 V. The circuit is to function as a digital inverter that meets two conditions:

1. An input of υS = 0 V must produce an output of υCE =5V.

2. An input of υS = 5 V must produce an output of υCE =0V Select a value of RB so that the circuit meets these conditions
