Zusammenfassung:The present disclosure relates to gate oxide protection circuits, which are used to protect the gate oxides of field effect transistor (FET) elements from over voltage conditions, particularly during situations in which the gate oxides are particularly vulnerable, such as during certain manufacturing stages. Each gate oxide protection circuit may be coupled to a corresponding FET element through corresponding first and second resistive elements, which are coupled to a corresponding gate connection node and a corresponding first connection node, respectively, of the FET element. The gate connection node and the first connection node are electrically adjacent to opposite sides of the gate oxide of the FET element. Each gate oxide protection circuit may protect its corresponding FET element by limiting a voltage between the gate connection node and the first connection node.
