Referring to your first schematic, why do you call ot current feedback?
It's not, but simply a conventional amp inverting voltage feedback. Output voltage will track input voltage, independent of load (that's the definition of voltage output), and gain will be 10K/100 ohms=100X .
What's so special about this very common topology?
Your second schematic does not make sense.
Where is the input signal applied to it?
Besides, it's open loop and *any* real world amplifier will have huge offset or even slam the output against one rail.
Stee is an artist; while having absolutely no clue of electronics, he's very good at assembling bits and pieces (from schematic chunks to device pictures) collected from the Internet and then assigning sexy names to those "designs".
While the entertaining value is certainly there, I would not bother to even try to take a closer look at his "design ideas", there's nothing of any technical value there.
