| 1. | The output is buffered by a common emitter amplifier.
|
| 2. | The heart of an I2L circuit is the common emitter open collector inverter.
|
| 3. | The common emitter voltage follows this change and goes down thus making Q1 conduct more.
|
| 4. | All amplifier stages used common emitter amplifiers.
|
| 5. | As a result, the common emitter resistor R E acts nearly as a current source.
|
| 6. | For a medium source impedance, a common emitter or common source topology may be used.
|
| 7. | Often a common base is used in this manner, preceded by a common emitter stage.
|
| 8. | As a result, the common emitter voltage and Q1 collector voltage follow the input voltage.
|
| 9. | The load line diagram at right is for a transistor connected in a common emitter circuit.
|
| 10. | In this case, the common emitter voltage and Q1 collector voltage are not suitable for outputs.
