PCB impedance calculator

PCB Impedance Calculator and Stackup Design in Altium Designer There are many demands placed on PCB stackup design. High-speed designs carry a requirement for controlled impedance, crosstalk control, and the need for interplane capacitance. Impedance in your traces becomes a critical parameter to consider during stackup design for high-speed PCBs, but the stackup will also influence crosstalk susceptibility and sheet capacitance between ground and power planes. While you can work out many of these details by Read Article

Integrated circuit CMOS load capacitance

How Load Capacitance on a Transmission Line Affects Your Signals If you ever read about transmission lines and integrated circuit datasheets, there is this seemingly mysterious quantity called load capacitance. This value depends on the geometry of the component lead connected to the transmission line, as well as the substrate material and distance to the reference plane on the integrated circuit die. When working with transmission lines, the load capacitance of a component has some important effects on signal Read Article
