What does the circuit in the above link do? We've been asked by a client to look into using this to combine power sources with different voltages into a "halfway voltage" power supply. E.g. Input 5V and 3V supply and out the other side comes a 4V supply. I can't make heads or tails of the circuit in the link. Simulations aren't matching up to what the breadboard proto does either; I can provide more details if anybody is curious, but neither supports a the requested use case. Any ideas?

Alternately, if you want to buffer the voltage divider, a simple power op amp circuit would be less of a bother, since its gain would be in the 99.9% range.

Wow... just wow...
Apart from that, if the FETs are depletion-mode types, the circuit will work. But those are scarce nowadays.
Benta.

RE: decipher this german circuit
on the circuit itslef:
This is not a circuit for signal processing but for power. In power elctronics e.g in Inverters connected to 400 V three-phase mains, electrolytic caps have to be connectec in series due to their Limitation in voltage rating. To balance the voltage parallel resistors have to be added, creating significant no-load losses. The circuit ensures proper voltage sharing with much lower losses.
