How to design a Voltage Averaging Circuit with low current

[kma]

Can anyone tell me how to get the Voltage Averaging Circuit design with low current, like V1=(V0+V2)/2?

Thanks

If V0,V2 is dc voltage, just use 2 resistors.
If V0,V2 is ac signal, use filter first? I am not sure.

Consider a T-shaped resistor network, where the horizontal branchers are of value R and the vertical branch is also of value R and is grounded at the other end.

The two voltages are applied to the two sides of the T-network. By simple mesh analysis, the current flowing in vertical branch is proportional to V1 and V2 respectively(Sinec R is constant)

By simple mesh analysis,the voltage at point x is
(V1/2R+V2/2R)*R
=>(V1+V2)/2

     R         R
V1<-------x------->V2
          |
          |
          | R
          |
          |
         GND

Sorry,It is really difficult to keep text-drawings intact even within code sections.
Note that, this may not work with high frequency signals without additional RC compensation.
