Webthe low-side MOSFET of a synchronous buck. Again, taking the gate voltage above the threshold does not automatically drive the device into a shoot-through-induced failure. VGS(th) is a MOSFET designer’s parameter and defines the point where the device is at the threshold of turning on. It is an indication of the beginning, nowhere near the end. WebThe amount of charge required for a MOSFET to begin to turn on (before dropping drain-source voltage) Gate-drain charge Q gd. The amount of gate charge charged in the Miller plateau. Gate switch charge Q sw. The amount of charge stored in the gate capacitance from when the gate-source voltage has reached V th Until the end of the Miller plateau

WebCgs and Cgd are the intrinsic gate-source and gate-drain capacitances of the MOSFET, and while they are relatively very small (50pF-700pF), my theory is that they are acting as a pass-through when Vin is first applied. WebThe Coss includes the capacitance between the drain and source structure, Cds, and the capacitance between the gate and drain, Cgd, Coss = Cds + Cgd Toshiba MOSFET Parasitic Capacitance Model In the switching operation, the power source charges Coss to store the energy during the turn-on phase.
