Guard ring structure
WebNov 1, 2024 · The structure is surrounded by a P+ guard-ring on the outermost side of the traditional interdigital structure. The cathode and P+ guard-ring connect to the ground while the anode connects to I/O pin. In different application scenarios, the connection of P+ ring will be different. WebRing guards come in a range of styles and designs. Here are the most popular ones: 1. Channel Set Ring Guard Channel set ring guard. See it here. This style features a row of diamonds or other gemstones set into a channel or groove in the metal band. The result is a sparkling band with diamonds held securely in place.
