| 1. | :It's probably because it's really a multiple of a base voltage.
|
| 2. | The emitter base junction is unchanged because the emitter base voltage is the same.
|
| 3. | As this base voltage increases, current begins to flow in the collector of Q1.
|
| 4. | V base1 and V base2 are the base voltages on sides 1 and 2.
|
| 5. | Computer models such as those used in SPICE use the collector base voltage " V"
|
| 6. | Some models base the collector current correction factor on the collector base voltage " V"
|
| 7. | Its collector-base voltage is zero as shown.
|
| 8. | The R 1-R 2 voltage divider conveys this change to the Q2 base voltage and it begins conducting.
|
| 9. | Typically, the collector voltage will be higher than the base voltage, and Schottky diode will be reverse biased.
|
| 10. | Its collector voltage goes down and Q2 begins going cut-off, because the voltage divider now provides lower Q2 base voltage.
