It’s time to find answers with this new video tutorial series that provides quick insights. This first tutorial starts with the basic question: why do data centers need PAM-4 at all? It also

Hi, I am trying to simulate a structure as below:   I have to attach an SMD diode between ports, P1 and P2. I have SPICE model for the diode and C2 and L2 model the package, whereas L3 is for DC path. Separtion between P1 and P2 is 45mils whereas the pad size is 80mil/40mil. Now, If I define port P1 and P2 as TML, the EM cosimulated
