※ 引述《konora (焦糖玛奇朵~(b))》之铭言：
: 大家好~
: 我有一个问题想请教各位
: 单一颗电晶体 输入和输出都接bias-T模拟
: 发现到高频时 都会不稳定.
: 这是什麽情形呢?
: 谢谢
You are doing simulation? Many reasons will cause oscillation,
especially at higher frequency. One of them is the feedback
path bouncing from mismatched port. At higher frequency,
parasitic capacitance and inductance will become larger and
lead to oscillation.
