Hello,
Inspired by the thriving ML-news google group community and the lack of any such community for ECE engineers, I have made an ECE news google group.
This group is made to serve as a forum for notices and announcements of interest to the electrical and computer engineering community. This includes events, calls for papers, employment-related announcements, etc.
Please join at: https://groups.google.com/g/ece-news
Anyone is welcome to join and grow this group. Meaningful posts and engaging members are quintessential for this to succeed.
I would also be looking for community managers if and when this community grows to a considerable size. Please spread the word to your peers, professors, and managers.
Thanks.

Why should you care? Just killfile him, and also those who keep

Kill filters confuse me, given the followups. But yes, s.e.d. is
pretty bad now.
I think we can make a TPS562208 into a pretty good +5 to -5 volt
converter. We're using an LM2662 charge pump now and it's soft and
noisy. You know the trick, ground the switcher output and its ground
becomes the negative out.

I once had a board with lots of PECL and some +3V stuff. I used the
+3V also to terminate the PECL, which dominated the +3V current, so
I used a negative regulator to make +3V. The layout guy was puzzled.

Anything's better than getting flooded with bunch of ignorant questions from people who don't even know basic electricity, and have no idea how that knowledge just may on the off chance be necessary to understand electronics...

John Larkin posts here to get flattered. He doesn't post anything that deserves flattery, and he doesn't like discussing how his schemes could be improved.
The very idea that they could be is insulting.
He's just told us that the phase detector in the 40406 is rubbish - when the circuit includes two phase detectors and the Philips HCT9046 has a sequential phase detector which has been modified so that it doesn't have flaw present in the original.
The 4046 is great for some things and I like its zero-crossing >phase-frequency detector.
But zero-crossing detectors aren't always what is needed. These
days, a micro is necessary if you want a multiplier phase detector
that doesn't cost a lot.

In the real CD4046B, the charge-dispensing phase-frequency detector
has a huge time deadband, which makes for lots of jitter and phase
noise.
There are some better versions.

We usually do it in an FPGA.

Do you add an ADC to that ? Or just use ones and zeros as input to
the FPGA ?

Time locking to picoseconds uses an ADC to digitize the time difference between two oscillators, and the FPGA uses that to servo one of the oscillators.

Jeroen BellemanThat still confuses me, using a linear regulator upside-down.
In a recent case, we had to plan for a buck switcher being driven
backwards, such that it would blow up the big caps in its input
supply.
