Reply To: Charge ac仿真中电极apply ac small signal 中的none all last分别是什么意思呢

[Guilin Sun]

参见说明 https://support.lumerical.com/hc/en-us/articles/360034918833-Boundary-Conditions-in-CHARGE-Simulation-Object APPLY AC SMALL SIGNAL: This option is valid only during small-signal ac simulations. The value is set to NONE by default. When enabled it applies a small signal AC voltage to the DC bias voltage.

• all: SSAC voltage will be applied to all bias points.
• last: SSAC voltage will only be applied to the last bias point.

如果不是仿真小信号分析，不用理会这个设置。
