WebIn the BJT schematics, the spacing between the p-type SiC guard rings 710 is illustrated as constant and only two guard rings 710 are shown for simplicity. In the disclosed BJT MFGR edge termination, the number of concentric trenched guard rings 710 , their thicknesses (widths), and spacings can vary in order to maximize the breakdown voltage. WebA 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 metal can op ...
