New book on amplifier design.

[Worldie]

An Analytical Approach to Linear Audio Frequency Power Amplifier Design: Selected Papers: Amazon.co.uk: Kiwanuka, Michael: 9781803691602: Books

Blurb from Amazon:

This book is essential reading principally for designers of linear audio frequency power amplifiers and more generally students and amateur enthusiasts of audio frequency electronics.

A first-principles analytical approach is here preferred because it engenders an intuitive appreciation of the workings of linear audio frequency power amplifiers, and it provides the engineer and researcher with a sound foundation for further work in the field.

Among other matters, the author cogently and succinctly

1. Evaluates the merits and demerits of two pole Miller minor negative feedback loop frequency compensation (TPMC) and localised two pole Miller minor negative feedback loop frequency compensation (LTPMC) and develops clear, systematic means by which these frequency compensation networks may be optimised.

2. Tenders two novel feedforward-compensated push-pull folded cascode transimpedance stage (TIS) designs in which slew asymmetry is banished.

3. Renders two novel feedforward-compensated push-pull transimpedance stage (TIS) designs based on the complementary emitter-coupled transistor pair of Sziklai et al.

4. Assesses the value of Burwen’s Inductive Frequency Compensation (IFC) in context.

5. Presents six idiosyncratic audio frequency power amplifier designs compensated with optimised LTPMC networks and incorporating non-invasive anti-saturation measures.

6. Examines monolithic/discrete composite linear audio frequency power amplifiers and their frequency compensation.

7. Describes how Safe Operating Area (SOA) protection networks may be correctly and accurately designed so that they remain inert when the amplifier does not require protection.

8. Gives an account of error feedback correction and presents three novel error feedback correction circuits.

9. Discusses output-stage-inclusive single pole Miller minor negative feedback loop frequency compensation (OSI-SPMC).

The author gives all credit to Almighty God, the fount of all knowledge and without whom nothing is possible, through His son, Jesus Christ.

Finally, the author hopes devoutly that adopters of this book will derive as much pleasure from reading it as he did from writing it.

The author has kindly provided LTspice files of three of his designs with "robust compensation". These files contain all the required models embedded in the schematics, so they are ready to run without any extra effort:

Knowing the author, there will probably be a lot of badmouthing of other authors/designers.
His years-long mission has been to discredit others. All in the name of God Almighty, of course.

As they say, the proof of the pudding is in the eating. Perhaps it might be a good idea to read it before passing judgment.

He had a number of identities here - probably "mikeks" was used the longest, going back more than 10 years ago. I don't doubt he was on the ball with audio electronics and did post a scholarly doc. or two here. The last I recall, being a paper on optimised VI limiter design but it seems he spent far too much time posting like a brat, with insults, stalling threads with mischievous comments and spreading confusion, as if it was his right and privilege to thumb his nose at others. Peers won't forgive or forget that but newer members may not be unduly concerned. https://www.diyaudio.com/forums/members/mikeks.html
- Just realised the book is in its in its 2nd edition - didn't catch the first.....

I just ordered it.

As it says, selected papers. I've read all of them already.
I believe I have interacted enough with him over the years to be able to pass judgement. But go ahead and form your own judgement.

[Worldie]

I've read all of them already.

The author says this statement is untrue, although he acknowledges that you have read some of them.

 

[jan.didden]

I'll take that risk.

[InspectorGadget]

Ohhh 'the author' says that?

 

[Ian Finch]

Worldie, are those replies contained in the book, another source of information on the author's views or are you actually more closely related to the author than you make out here?

 

[jan.didden]

'The Author' has roamed these threads under various handles and sockpuppets, only to be banned or leaving of his own accord. Who is to know who this anonymous 'Worldie' really is?

Jan

 

[InspectorGadget]

That was my inference also ...

Seems kinda defensive too, for someone unconnected ...

 

[stinius]

I have browsed through some of the posts by Worldie and IMHO he is definitely the same person known as Mikeks.
For those that buys the book or that has already read the masterpiece, it would be interesting to know what he says about CFA.

Shouldn't this be in vendor forums?

If you take a look at LTspice files he provided in first post, definitely no CFA.

 

[Tibouchina]

It is a popular book.

- Just realised the book is in its in its 2nd edition - didn't catch the first.....

• First edition was available 1st June 2021.
• Second edition released 19 Nov 2021.

A very popular book much in demand ... If you want to understand the author's prior pyschology perhaps it is worth reading Beyond Symbolic Politics: Reframing the Convergence of Fiscal Decentralization and Political Accountability in Uganda and Thai Municipal Gov'ts: Amazon.co.uk: Kiwanuka, Michael: 9786202800396: Books

I think I'll order the Linear Audio USB stick instead.

Beware of what you find on internet (Wikipedia) such as:
' [Michael] Kiwanuka has openly stated he has struggled with anxiety and other mental health issues'
Not sure it's related.

 

[InspectorGadget]

I would have thought that was pretty obvious. Chronic narcissism doesn't just come out of nowhere.

 

[Ian Finch]

There are other Michael Kiwanukas. They can't all be the same person so be careful not to slander the wrong guy. e.g Michael Kiwanuka - Wikipedia

Around 2005, Michael Kiwanuka expressed the same perplexity about the term CFA that I had previously expressed in a post here. In 2017 in AudioXpress, he clearly explained why the function attributed to the term for the past forty years was spurious (Peter Baxandall and Ed Cherry had done the same around 1990). I opened a thread here about it shortly afterwards.
