This simple mosfet power audio amplifier circuit, with TL071C and 2 MOSFETs (IRF9530 and IRF530) can deliver up to 45W on 8Ω speaker or 70W on 4Ω speaker. This schematic is based on Siliconix ...

I've noticed that my 2 year old daughter has an unhealthy interest in my current, ... Simple 2.0 digital amplifier. Thread starter ...

Learn how to build your own MosFET amplifier from scratch with ease. This step-by-step guide will walk you through the process of creating an amplifier that delivers superior sound quality and ...

The design is classic and simple: a 5 V regulator IC, a Hall effect sensor, a 741 op amp, and a MOSFET to turn the electromagnet on and off. Sure, there are a few passive components and a diode ...

When a MOSFET or IGBT gate-threshold voltage is higher than the available drive voltage, it's standard to use an op amp or other driver to bridge the difference. This circuit ...

In some situations, it becomes necessary to drive a MOSFET (or IGBT) with a voltage that’s lower than its gate-threshold voltage (V Th). This is usually done with a driver or op amp to boost the ...
