Re: How to design a Voltage Averaging Circuit with low curre
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
Code:
R R
V1<-------x------->V2

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.
