This is as good an explanation as I could have hoped for. ?I really appreciate your insight on this... it makes sense. ?Perhaps it¡¯s just a missing feature in LTspice, or perhaps it¡¯s by design somehow.?
I have used 0V supplies in the past for current detection. ?In this case I just went for a quick calculation, and it worked until I tried a subcircuit and found this hitch. ?I guess I learned something in the process, but I think I¡¯ll go back with using the 0V supply as a reliable method. ?Thanks for the nudge. ;-)
I also totally understand the coffee thing, and I can relate. ? Ha! ?
Thanks again!
