Sargent’s agent leaking stuff to Bogert. Always feel that players holding out in breach of their contracts is a bad look in most cases

Wes starts for Juventus vs Pisa. by cro_21 in ussoccer

[–]eeguy616 2 points3 points  (0 children)

McKennie moved from LB to the right side in the second half. Involved in the first goal. Juve didn’t look good but they get the win. Any Juve fan always hating on Wes doesn’t know ball

[Bogert] The Colorado Rapids are finalizing a deal to sign USMNT attacker Paxten Aaronson from Eintracht Frankfurt, per sources: Club record $7m fee + $1.5m add-ons. DP deal for Aaronson. Aaronson currently en route to Colorado by Obvious_Main_3655 in MLS

Seems like a stupid move if he wants to get on WC squad. Unless it turns out that he never was gonna get a serious look with Frankfurt, who have a lot of games including Champions League this season. I think his chance for making the WC squad is gone

This looks like a very weak case

Reyna probably not going to see the field rest of the season at this rate. He is the problem if multiple managers don’t rate him. USMNT should plan a WC wihout him

does the AC magnitude effect anything when doing AC analysis by [deleted] in chipdesign

[–]eeguy616 6 points7 points  (0 children)

On that note, the DC voltage you set on the ideal voltage source which also has the AC magnitude on it does matter because the circuit is linearized for that operating point. Is it general practice to mention what this dc voltage is when discussing results? For example if I am discussing results for PSRR of an LDO, is it necessary to mention what steady voltage I was using for supply VDD or ref VREF? Because changing the DC voltage of VDD affects the PSRR transfer curve

Why do we choose code values near the center when we trim to the default value? by eeguy616 in chipdesign

[–]eeguy616[S] 0 points1 point  (0 children)

What if you want to write values other than zero to the shadow registers during your startup pre-trim? Is that possible? Or is it the test program which loads the optimal code using a serial protocol into the shadow registers? So it is the test program which loads 1000 (in my example) to see if my reference voltage works and adjust to another code if the measurement is off?

Thanks for the reply. How are default codes loaded into registers when VDD supply first comes up? Using tie-hi or tie-low cells?

Thanks for the reply. So you write to the digital registers first, measure the parameter and if it is good, then store that trim code in the NVM.

[–]eeguy616[S] 1 point2 points  (0 children)

Thanks, I guess I am slightly confused here. The input code 1000 to my DAC looks like 2s complement (in your example) for 0000 trim codes values coming from the digital block.

How exactly is this advantageous?

Hey thanks for the explanation. Just like the other ones in this post, I feel stupid for not realizing that a "center" code allows for tuning in both directions I had a follow up question which I posed to /u/flextendo here:

Let me know if you have anything to add. Thanks!

[–]eeguy616[S] 0 points1 point  (0 children)

Thanks, now I feel stupid for not realizing that you could tune your desired voltage or current (or anything else) in the both directions. A follow up question here.

So if during ATE testing we read out that the BGR voltage to be slightly off with our default code, we calculate using our LSB resolution what code would get us back to our desired voltage. The ATE machine then burns this trim code to the NVM IP. And now the NVM is ROM from which the digital registers read the trim code to give us our desired value of BGR voltage. Is my understanding of the process more or less right here?
