: Fig.(c)的transistor的基極端
: 要用哪一種等效呢 然後要怎麼等效呢
: 麻煩替我解惑一下 感謝了
equivalent circuit?
I guess that you mean "small-signal equivalent ckt"
we can use T-model to estimate this circuit
Collector - 10k-ohm to ground, Vc
passive current source gm*vbe between Collector and Base, toward Base
Base - 10k-ohm to ground and vi
re between Base and Emitter
Emitter - 10k-ohm to ground, Ve
