パワーMOSFET（英語：Power Metal-Oxide-Semiconductor Field-Effect Transistor）とは、比較的大きな電力を扱えるMOSFETのことを言います。従来のバイポーラ・トランジスタに比べて、スイッチング速度が高く、低圧領域（～200V程度）においてオン抵抗が低い点が特徴です。

I am driving a MOSFET with a typical input capacitance of around 2800pF with an LM324 R-R op amp in the linear mode using a standard function generator. Unfortunately, the LM324 cannot drive the ...

Currently I am building a MOSFET Audio amplifier based on LME49830 chip from TI. The scheme consists: My power supply contains 2 PSU, the first one delivering +-60V to the POWER AMPLIFIER BOARD and ...

I can't let go of them. Over ten years ago, when I was a pennyless student, I lusted after the Luxman LV-103. This was a big and well-equipped e900 integrated amplifier with a tube voltage gain stage ...

The MOSFET pulls down on the bottom of the solenoid to increase the solenoid current ... Similar circuit to Figure 6 but with solenoid grounded, so freewheeling forces inputs negative. Providing ...

An audio power amplifier or a power acoustic amplifier can be used to amplify audio transmissions. A microwave amplifier or MOSFET amplifier may be used for high frequency applications. Other power ...

To drive a MOSFET requires more than merely a logic level output, there’s a requirement to charge the device’s gate which necessitates a suitable buffer amplifier. A variety of different ...

By Richard Frey, P.E. In this paper, we report on the design and evolution of a 500W, 27 MHz Class E amplifier. It doubles the operating frequency of previous high efficiency amplifiers using MOSFET ...
