Consider the emitter diffusion capacitance Cde of a BJT.
Which of the following statements is correct?
(a)If the emitter current increase , Cde decrease.
(b)If the base width increase,Cde decrease.
(c)The large the value of Cde,the smaller the unity-gain frequency fT.
(d)If the BJT is operated in the active region,Cde is smaller than the
collector junction capacitance.
答案是給C
不過我是覺得B
有大大可以幫忙解惑嗎?
