Web6 Jan 2024 · Splitting the ground plane under the component creates an unwanted side effect. Signals that must cross from one side of the cut to the other don’t have a path for their return current. That current will find another way to return to its source, which can lead to signal integrity or EMI problems. Noise enters the analog signal loop in two ways. Web23 Apr 2024 · Splitting your PCB ground plane in this way makes it difficult to define a clear return path, leading to large loop inductance, incorrect impedance, and radiated EMI. Split …
