Comment on How The End Of The USSR Changed Eastern Europe by Alex Hiley

Well worth visiting the capitals of Estonia, Latvia & Lithuania. They are proudly independent but the situation is complicated by having a lot of Russian speakers in the eastern parts. Also they only have populations of about 2 million each – so if they weren’t part of NATO, Russia could invade them in an afternoon.

In recent years a lot of my holiday flights have been on 737s but they don’t advertise the “Max” bit. In the safety card it might be called a 737-800, but if you go up the rear entrance steps you can see 737-Max in small print on the outside. I wonder how many people would have cancelled if they knew ?

In reply to Fred Dart. Absolutely Fred and Valgamaa spot on - it was Hans Camezind with Interdesign.

Also may be a typo and perhaps it was 52 not 72 years ago.

In reply to Fred Dart. Was the company Interdesign?, I have one of their booklets with lots of useful bipolar i.c. designs which also had the Ferranti logo if I remember correctly.

In reply to Eric. It is indeed, Eric. Thanks. I'll change it ASAP!

Comment on 112 x 62mm IGBT module for 1kV flying capacitor boost converters by Mike Bryant

In reply to DB. It simply charges up two capacitors in parallel, usually from a third much larger capacitor, then 'flies' the second capacitor into a series arrangement with the first capacitor, hence giving twice the peak voltage. This then charges a fourth capacitor up to this voltage and keeps it there by switching at about 10kHz. Compared with traditional switch-mode PSUs, there is less stress on the transistors, but the capacitors do age. In theory you are limited to multiples of the input voltage, but you can do tricks using smaller flying capacitors to achieve other voltages.

Is the title supposed to say AOSP?

Comment on Horrible Uncertainty by Jack Browne

Malcolm gets the big picture. If you don’t understand the markets, you can’t find, lead and devend your key markets.

The semiconductor market is a lumpy business. Big investments, fabs, Chip teams all chasing new opportunities created by Moore’s law – 2x every other year perf or ½ power – choose wisely.

Fickle consumers buy the shiny new pet rock (Peletreon, Starliner), while leaders focus on the prize and create value – AI moving to the wedge.

Connected and Smarter devices far outnumber people.
Help us see the prize Malcolm

Swiss and PLL makes me think of Hans Camenzind, so the chip must be the 555. The Ferranti connection was new to me, but Wikipedia records the sale of Interdesign to them so confirming my thoughts.
