Web4 Answers. A guard ring is traditionally used to protect high impedance nodes in a circuit from surface leakage currents. The guard ring is a ring of copper driven by a low-impedance source to the same voltage as the high impedance node. This would typically be the input pin of an op-amp. Here's an example of a classic guard ring layout for a ... Webtermination structure eliminated the need for P+ guard ring. In addition, with the field oxide and field plate recessed below the silicon surface, the manufacturability of sub-micron features is significantly improved. (Figure 2) Figure 2.
