嗨,专家们,我在ADS原理图设计中有一个问题,如果你能帮助我,我将不胜感激。
我有一个s2p(从HFSS导出的与串联阻抗相关的两个端口散射参数)文件。 现在,我有了基于S参数提取串联阻抗的公式。 我想把这个阻抗文件放在简单的微带匹配电路中。但是,我找不到可以通过公式计算阻抗并提供S参数的链接。 如您所知,有一个选项命名为“基于线性方程式”的一个端口Z,我可以将其用作ADS中的串联阻抗,但我不能将方程放在其中并将公式链接到提供的S参数。 如果您有任何解决方案,请告诉我。 以上来自于谷歌翻译 以下为原文 Hi expert guys, I have a issue in ADS schematic design I would appreciate you if you can help me. I have a s2p ( two port scattering parameters exported from HFSS related to series impedance) file. Now, I have the formula to extract the series impedance based on S parameters. I want to put this impedance file in simple microstrip matching circuit.But, I cannot find a link that can calculate the impedance by the formula and provided S parameters. As you know, there is an option named as " linear equation based" one port Z that I can use as series impedance in ADS, but I cannot put equation inside of it and link the formula to provided S parameters. Please let me know if you have any solution for it. |

如果要将S2P数据的系列分支用作单端口,则有一种更简单的方法。
您可以使用S2P数据项,使参考节点保持浮动状态,并将电路连接到S2P元件的引脚1和2。 通过此连接,您可以在S2P元件的引脚1和2之间连接2端口数据的串联阻抗,并且分流元件断开(断开)。 以上来自于谷歌翻译 以下为原文 If you want to use the series branch of your S2P data as a one-port, there is a much easier method. You can use the S2P data item, leave the reference node floating and connect your circuit to pin 1 and 2 of the S2P element. With this connection, you have the series impedance of the 2-port data connected between pin 1 and 2 of the S2P element, and the shunt elements are disconnected (open). |

lmksa 发表于 2018-12-28 08:25 非常感谢。 听起来很棒,可以帮助我。 另外,如果我想提取阻抗并将其用作电路建模中的电路元件,我需要阻抗模型。 你有什么想法吗? 你的想法很好,因为我想要S参数模拟,但我还需要电路建模和简单的电路仿真。 以上来自于谷歌翻译 以下为原文 Thanks a lot. It sounds great and can help me. Also, if I want to extract impedance and use it as a circuit element in circuit modeling, I need impedance model. Do you have any idea about it? Your idea works well as I want S parameter simulation, but I need also circuit modeling with simple circuit simulation. |

> {quote:title = Taha写道:} {quote}>如果我想提取阻抗并将其用作电路建模中的电路元件,我需要阻抗模型。 你有什么想法吗? 您可以采用不同的方式,具体取决于实际的数据/组件。 您可以查看Z11或Y11,转换为一个端口阻抗(R + jwL,R + 1 / jwC,R || jwL,R || 1 / jwC)。 如果设备/电路简单,这可能会很好。 您可以根据已知的物理结构为更复杂的模型创建自己的模型,并计算/拟合参数,如我在此为RFIC电感器所示:http://muehlhaus.com/products/equivalent-circuit-model-fit- for-rfic-inductors你也可以尝试ADS内置提取窄带或宽带SPICE模型。 在ADS帮助中,它在此处记录:主页>仿真>模型创建>窄带SPICE模型生成器 以上来自于谷歌翻译 以下为原文 > {quote:title=Taha wrote:}{quote} > if I want to extract impedance and use it as a circuit element in circuit modeling, I need impedance model. Do you have any idea about it? Different ways you can do it, depending on the actual data/component. You can look at Z11 or Y11 and convert is to one port impedance (R+jwL, R+1/jwC, R||jwL, R||1/jwC). This might work well, if the device/circuit is simple. You can create you own model for more complex models, based on known physical structure, and calculate/fit the parameters like I have shown here for RFIC inductors: http://muehlhaus.com/products/equivalent-circuit-model-fit-for-rfic-inductors You can also try the ADS built-in extraction for narrowband or wideband SPICE models. In the ADS help, it is documented here: Home > Simulation > Model Creation > Narrowband SPICE Model Generator |
