How To Handle Current Return Path for Better The Signal Integrity
Before we start with today’s article, something needs to get engraved in your minds. If some current goes out somewhere, it will always come back to the source, with no exceptions. Hence, there is always a current loop, a current return path along with the current-carrying traces. So, the current does not really care if you provide it that return path, it will find its own. But if you do not, it will interfere and mess around with your entire circuit, while finding its own way back.
