Transistors - 2 Flashcards
A common base amplifier has:
More voltage gain than common emitter or common collector
What does it mean for a transistor to be cut off?
There is no current between emitter and collector
An emitter-follower amplifier has:
More current gain than common emitter or common base
What conditions exists when a transistor is operating in saturation?
The base-emitter junction and collector-base junction are both forward biased
For current to flow in an NP silicon transistor’s emitter-collector junction, the base must be:
At least 0.7 volts positive with respect to the emitter
When an NP transistor is operating as a Class A amplifier, the base-emitter junction:
Is forward biased and the collector-base junction is reverse biased
