WebEffect of Coupling Capacitance In deep sub-micron technology (i.e. <130nm) and below, the lateral capacitance between nets/wires on silicon, becomes much more dominant than the inter layer capacitance. Hence, … WebJun 18, 2024 · Capacitive/Electric Coupling. In addition to a magnetic field, current flowing through a PCB trace also generates a corresponding electric field. When an electric field from one trace contacts an adjacent parallel trace, a capacitor is created. When two lines are capacitively coupled, it’s possible for the signal on one line to induce ...
