WebJul 1, 2012 · In the first part of this paper, the design of an implantation-free guard ring assisted etched JTE using finite elements simulations is detailed. Then the fabrication of … 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 ... Web2.1.2 Guard Rings. The Guard Rings (GR) Termination is a famous alternative to the JTE. Figure 2.6 – Guard rings on vertical PiN Diode termination. It is made of highlyP + -type rings, surrounding the active area (see figure 2.6). Unlike the JTE, the doping level of the rings has no major influence on the termination efficiency. eastern kentucky university forensic science
