Hi, :
?
The UniversalOpamp model really makes sense, it draws lots current flow.
Since it hurts because of the larger power dissipation, so I give a shot by using local 'AD746', it draws much fewer current, though possibly could be adjusted by external parameters, more efforts needed.
Above ~2.29Hz, the common mode impedance will be larger than differential mode impedance about starting with 9.8G. (Same as gravity value) Apply the common sense rule, common mode impedance should be greater than differential mode.
?
Maybe I don't have the common sense, knowing so much different things all over the world, eg: I haven't noticed the 'common mode > differential mode... things'. But still eager to learn more.
Maybe something is inevitable ,eg: Unfortunately, we can't know/fix every bug, same as the laplace transformation issue mentioned before, see below: That one broken my heart, (sorry correct to ) religion.
?
All models should play happily, but the simulator platform mechanism always alternate between bright & dark, peak & valley. Sooner or later, unfortunately.
Which , I mean in the file I changed from the UniversalOpamps to AD746, it plays very sadly not going right in new simulator LTspice V.24.1.5 , which I modified it in LTspice XVII V.17.0.37.0, and when migrate it to run in new one , it feedbacks the following message:
