Do you really need ground for differential pairs in PCB design? In this video, Tech Consultant Zach Peterson dives into the science of differential impedance, the role of ground planes, and how trace spacing impacts high-speed designs.
Learn why differential pairs are self-referencing and how they help reduce EMI in your circuits. This guide will simplify complex PCB concepts and boost your design skills, so be sure to check it out!
**Topics Covered:**
- Differential impedance explained
- Impact of ground plane proximity
- How substrate thickness affects PCB design
- Real-world examples in Altium Designer (free trial link below)
