我找到了cadence里面关于port的说明,但是我不方便放图。在cadence help的Analog Library Reference文档里面,搜索port就有了。
它里面对port的描述是:The port component is an independent resistive source tied between positive and negative terminals. It is equivalent to a voltage source in series with a resistor, where the reference resistance of the port is the value of the resistor。
关于Reactance的描述是这样的:The imaginary part of impedance is used for harmonic balance large and small-signal analyses, and for the ac, noise, xf, sens, stb,pz, and sp.analyses. The reactance is not used for dc, tran, and shooting-bases large and small-signal analyses。
所以对于port本身来说,他就是没有虚部的,虚部是port之外的东西,然后一些仿真比如说瞬态仿真会直接无视掉这个虚部。
