How to Reduce Ground Bounce: Mitigating Noise with PCB …

WebGround bounce on a PCBA is when the voltage level of a ground reference changes value or “bounces” to a different value. This phenomenon is usually associated with gate switching within transistors and ICs, and if significant enough, can cause erroneous circuit operation. WebSep 25, 2024 · Typically on the PCB, you can have a chassis ground connection as described above and the connection to the earth ground for safety. Meanwhile, you should have a ground plane on the PCB that supports both analog and digital return paths; you should not have physically separated ground nets. toddler pink sequin pants
