Repetitive short circuit capability of SiC MOSFET at specific low gate-source voltage bias for more robust extreme operation

Low Voltage SC Circuit Design Using Short-Channel MOSFET Switches

Analog switches, which are known to be the bottle-neck for reducing the supply voltage, are analyzed. MOSFET transistors with channel lengths shorter than the minimum feature size (L 0 ) in a given technology are proposed for use as switches operated at a low supply voltage. These MOSFETs have lower threshold voltage and higher punchthrough currents compared to a transistor of L 0 length (due t...

Characterization of the gate-voltage dependency of input capacitance in a SiC MOSFET

The charge/discharge phenomenon of capacitance between terminals in a power MOSFET affects on its switching behavior of the device. The input capacitance is composed of the gate-source capacitance CGS and the gate-drain capacitance CGD, which vary with gate voltage VGS. This paper characterizes the relationship between the input capacitance of a SiC MOSFET and the gate voltage with considering ...

Modeling and Design of a Low-Voltage SOI Suspended-Gate MOSFET (SG-MOSFET) with a Metal-over-Gate Architecture

A novel MEMS device architecture: the SOI SGMOSFET, which combines a solid-state MOS transistor and a suspended metal membrane in a unique metal-over-gate architecture, is proposed. A unified physical analytical model (weak, moderate and strong inversions) is developed and used to investigate main electrostatic characteristics in order to provide first-order design criteria for low-voltage oper...

Short-circuit protection for an IGBT with detecting the gate voltage and gate charge

This paper proposes a new short-circuit protection method for an IGBT. The proposed method is characterized by detecting not only gate charge but also gate voltage of the IGBT. This results in a shorter protection time, compared to the previous method that detects only the gate charge. A real-time monitoring system using an FPGA, A/D converters, and a D/A converter is used for the proposed prot...
