The Re transistor model
Common Emitter Configuration
- Vi is equal to Vbe
- Input Current is the base current
- Equivalent circuit
- Input is represented by a single diode with Ie as current
- Will be replaced by re = 26 mV/IE
- Output: is represented by a controlled source
- Magnitude: Beta x Ib
- Input is represented by a single diode with Ie as current
Early Voltage
- Characters have slopes which is the Zo
- Steeper slope: less Zo
- Steeper slope: less ideal
- Desirable: Large Zo
- Avoids loading down next design
- Definition
- Intersection when slope of the curves is extended
- Discoverd by James M.
- High Ib, Higher slope
- Increase in Zo while Ib and Ic increases
- Larger collector current, less outout impedance
- Characters have slopes which is the Zo
