WebMar 4, 2024 · If this gate bounce exceeds the MOSFET’s threshold voltage, then cross-conduction occurs and the MOSFET can turn on when it should be off. If both the high-side and low-side MOSFETs turn on at the same time, shoot-through current occurs between the power rails causing major power losses and potentially destroying the MOSFET. WebFeb 13, 2024 · The DC sweeping data can be interpreted in double logarithm scale to analyze the conduction mechanisms. 98 For example, in the Fig. 4e, the DC sweeping current–voltage curves from an Ag/ZnO/ITO memristor was plotted in double logarithmic coordinates during the SET process. 99 During initial HRS within low positive bias …
