Evaluating my CLM-s Transistor-/Component- Level models for LM321/358/324

Update : The predecessors of the  below - the internals of the LM324 equivalent circuits are irrelevant - the purpose here is to provide a multitude of random ways to make the models to show up their weak spots



®-lly oriented for +5(±2.5)V Vs (!Only) - now up to ±15V "verification"

TEST.1


TEST.2


Update.2 ::

TEST.3


TEST.4

Note : the Test.4 is slow ramping , pos.-feedback oscillator -- usually the very fast or very slow ramps do trigger instabilities in the voltage comparators and in some op amp.-s (notice , that the previous tests didn't reveal any serious "bugs" /!\) . . . here we got 3 failed (unstable) , 3 - poor (it's "unexpectedly") , 1 strange (a macro-) model ... and 1 decent simulation model (!!! but not an exact functional analog of the LM321)
