Talk:Miller effect

Potential improvements
I appreciate the work that has gone into this article, but I'm finding it hard to follow. As someone who is familiar with the concepts but not an expert, I hope someone can take these suggestions and use them to improve things.

The first thing that would be helpful is to define feedback capacitance, which is first used in the opening paragraph. If you google that term, the top result is this article. It's possible to intuit what it means, but it'd be better to avoid uncertainty so that readers can feel more confident in the understanding they glean from the article. For example, is C an inherent property of the device which might be discovered in a datasheet? How would you measure or otherwise derive the value of that property? Is it something you can calculate from typical charge and capacitance parameters (e.g. Qg/Qgs/Qgd, Ciss/Coss/Crss) for semiconductor devices?

Another thing that would be helpful is to provide some examples of circuits that aren't ideal amplifiers. While the existing examples in the article do come up in real-world design scenarios, there are more common ones that have clearer impacts on circuit performance and behaviour. A brief practical example of the impact of Miller capacitance on MOSFET switching rates and switching losses would be very helpful, since it's one of the first challenges that a hobbyist EE might run into. It'd be very helpful to see a worked example that goes from typical datasheet parameters through to the practical limitations imposed by the Miller effect.

 * Hello. Thanks for the suggestions.  I will consider adding to the article, but you may be disappointed.  Wikipedia is not intended to be a text-book or how-to manual.  For that you would be much better off seeking out applications notes from manufactures, such as International Rectifier’s application note AN-994. Constant314 (talk) 19:22, 16 February 2021 (UTC)
