What seems to be the same article was published in a book:

MOSPOWER applications – 1984 - Rudy SEVERNS
Publisher: Siliconix, 1985
ISBN 10: 0930519000 ISBN 13: 9780930519001

This is the most MOSPOWER info ever put between two covers.

You can buy your own for not a lot of money.

Thank you for this posting.
By chance I have discover various BIAS servo IC's like Pioneer's PA0016 - go to
Предложено На Форуме - Страница 2 - Усилитель мощности А. Лайкова - Форум по радиоэлектронике
Are the internal circuit from the attachment well suited as a replacement for common vbe multiplier? Or should I prefer one of the other showed designs (JVC's VC5022, ROHM's BA3122N or one of the discrete design's) ?
What are the pros and cons of each ?
Check out also post #15 under
Help with schematic
Thank you very much for advices.
