A power MOSFET is a specific type of metal–oxide–semiconductor field-effect transistor (MOSFET) designed to handle significant power levels. Compared to the other power semiconductor devices , such as an insulated-gate bipolar transistor (IGBT) or a thyristor , its main advantages are high switching speed and good efficiency at low voltages.
The silicon-based RF LDMOS (radio-frequency LDMOS) is the most widely used RF power amplifier in mobile networks, [2] [3] [4] enabling the majority of the world's cellular voice and data traffic. [5] LDMOS devices are widely used in RF power amplifiers for base-stations as the requirement is for high output power with a corresponding drain to ...

The technology used a 32 nm SOI process, two CPU cores per module, and up to four modules, ranging from a quad-core design costing approximately US$130 to a $280 eight-core design. Ambarella Inc. announced the availability of the A7L system-on-a-chip circuit for digital still cameras, providing 1080p60 high-definition video capabilities in ...
FlexFET is a planar, independently double-gated transistor with a damascene metal top gate MOSFET and an implanted JFET bottom gate that are self-aligned in a gate trench. . This device is highly scalable due to its sub-lithographic channel length; non-implanted ultra-shallow source and drain extensions; non-epi raised source and drain regions; and gate-last fl
The power scaling which is now a major driving force in the industry is reflected in the simplified equation shown in the figure—critical parameters are capacitance, power supply and clocking frequency. Key parameters that relate device behavior to system performance include the threshold voltage, driving current and subthreshold characteristics.
Power MOSFET (Advanced Power Electronics AP9870GH) TO-252, also known as DPAK [1] or Decawatt Package, is a semiconductor package developed by Motorola [2] for surface mounting on circuit boards. [3] It represents a surface-mount [4] variant of TO-251 package, and smaller variant of the D2PAK package.
The enhancement device can also be used with a more positive gate bias in a non-saturated configuration, which is more power efficient but requires a high gate voltage and a longer transistor. Neither is as power efficient or compact as a depletion load. Depletion-load circuits consume less power than enhancement-load circuits at the same speed.
