Imbalanced voltage sharing during the turn-off transient is a challenge for series-connected silicon carbide (SiC) MOSFET application. This article first discusses the influence of the gate-drain discharge deviation on the voltage imbalance ratio, and its primary causes are also presented and verified...
The drain node of the diode-connected MOSFET is connected to the gate input node of the semiconductor device. The source node of the diode-connected MOSFET is connected to the gate of the power MOSFET. The power MOSFET and the diode-connected MOSFET are integrated into the substrate of the ...

In this paper, a semi-analytical model for the gate-to-source/drain fringing capacitance (Cf) of MOSFET including process variations is presented. Cf is defined as a layout-dependent parasitic capacitance separated from gate-to-contact capacitance (Cco), and is composed of several dual-k perpend...
Then, the relation between the drain current and oxide thickness will be modeling. The result is a nonlinear and parabolic relationship between the drain current and oxide thickness. To ensure the authenticity of the obtained model, a MOSFET parameters, based on 5 m CMOS technology was designed....
We use LM5050 to control three low-Rdson MOSFET(60V/1.4mohm) as a Oring-Diode for 28V/100A output. A separated 10V auxiliary power to supply this IC, and OFF pin was connected to GND, The abnormal occurred in the no-load and light load condition, we ...
