Very clear and good explanation, thanks, 5 stars.

Thanks radioam. I can create other videos... just let me know what topics are of interest to you.

Thanks! My question is: how to get power Mosfets (useful for audio) in a linear mode, so that they can be used as linear audio loudspeaker amp. I dont have much experience with that issue in relation to power Mosfets (know the principles of bipolar types and can apply them). Do Mosfets also have a linear and a non linear part in their characteristic? And how to set them to these parts? What is the relation to their treshold voltage (if they have that...).

As I understand it MOSFETs are transistors that a mostly used for switching, and with good reason. I have seen kits that use MOSFETs in a linear mode, I'm sure it won't be too hard to find some designs on the internet.

I have a small request (:

Could you please re-upload your electronics videos? They were great but they are of no use if no one can view them.

I have designed a very simple audio amplifier based around the Analog Devices ADAU1592 with much success. This video is really insightful as I am working on a dissertation that is based around Class D usage compared to other less efficient Class types.

As already said, I also recommend Analog Devices for any op-amp/audio semiconductors - my initial Class D amplifier design had a severe fault with the FET controller IC, using the ADAU1592 my design became very basic but it worked straight away!

Hi ShankyPistol, Thank you for selecting ADI's Class D Amplifiers and for your other product recommendations. Good luck with your dissertation.
