[starshipraider] azonenberg 94a084b - Updated resistor-characterization with more stitching vias
<azonenberg>
Oh... I know there's a few folks here who have done digital design on sky130
<azonenberg>
Anybody tried analog / RF design?
<azonenberg>
i'm dreaming of doing active probe amplifiers on one of the open processes at some point
<azonenberg>
miek: what bugs me more is that my ISI channel board has the same problem
<azonenberg>
and that was somewhat pricey. but if i need to tweak that, i also have some other things to twiddle on the 55mm line and maybe replacing it with an even longer one instead
<azonenberg>
miek: hey good news
<azonenberg>
checking oshpark order history
<azonenberg>
i dont think i ever actually ordered v0.1 of the beatty
<azonenberg>
So no wasted money lol
<miek>
hah, nice
<azonenberg>
i thought i ordered it then ran the sim just to have a baseline to compare measurement to
<azonenberg>
but it seems i actually was smart and gated the order on the sim
<miek>
i'll probably wait till you try out yours, but i'm down to get a copy and compare results on my TDR & VNA here
<azonenberg>
also this is a new record for me in pipeline depth i think lol. six different designs at oshpark for fab *and* two more in transit from oshpark to me
<azonenberg>
One of the ones coming tomorrow is the 10/100/1000baseT directional coupler tap
<azonenberg>
i'm excited about that one, I want to finally see some PAM-5
<azonenberg>
The other one i'm excited for is a test board with a SMPM footprint and a SMA
<azonenberg>
the idea being to TDR/VNA the SMPM launch I use in my probes and see if I can tweak it at all
<azonenberg>
And yeah the Beatty was intended in part as a control to test my own TDR setup more exhaustively
<azonenberg>
a step of known impedance that i can validate everything against
<azonenberg>
it might be a while before I can verify it, though
<azonenberg>
i just ordered the new rev today
<azonenberg>
and while I can VNA is when it gets in, i'm about to send out my 16 GHz scope for upgrades
<azonenberg>
it's getting turned into an SDA 816Zi-A instead of a base 816Zi
<azonenberg>
Not the current gen -B (yet) but it's a step towards that
