3. Modos de operação 4. Conexões em circuitos
7. Parâmetros do transistor α – Common base current gain β – Common emitter current gain γ – Emitter injection efficiency δ – Base transport factor
12. Expressões para os parâmetros do transistor γ = IEp/IE– Emitter injection efficiency δ = ICp/IEp– Base transport factor α = γ.δ = ICp/IE– Common base current gain β = α/(1- α) – Common emitter current gain
