Page 5 of the following says that when selecting the low-side FET in a synchronous buck converter, the Qgd/Qgs ratio should be as low as possible. It says that this is to reduce shoot-through due to spurious on-turning of the low side FET when the top fet turns ON. However, if this were the case, then all one would have to do would be to add a capacitor from gate-to-source of the low side FET. Wouldn’t you agree?
