FesZ Electronics | LTspice tutorial - Differential transmission lines @FesZElectronics | Uploaded November 2023 | Updated October 2024, 4 hours ago.
#208 In this video I look at how a differential line can be modeled using LTspice. In general when modeling differential transmission lines, you don't just model the line to line coupling, but you also need to consider the line to ground coupling as well. Based on the lines exact geometry different couplings will exist, and an accurate model will need to consider this.
