    Abstract: Examples herein describe techniques for isolating portions of an IC (100) that include sensitive components (e.g., inductors or capacitors) from return current (330) in a grounding plane (415). An output current generated by a transmitter (105) or driver in an IC can generate a magnetic field (405) which induces return current in the grounding plane. If the return current is proximate the sensitive components (305), the return current can inject noise which can negatively impact other components in the IC. To isolate the sensitive components from the return current, embodiments herein include forming slots (500) through the grounding structure which includes the grounding plane on one or more sides of the sensitive components.
