If we want to create fully differential and balanced outputs, and if we don’t have a single ended to differential ended converter/driver, can we use the following scheme neglecting the voltage divider DC errors?:
The idea is to create same common mode noise at HI and LO nodes. VCM is the source model for the common mode interference capacitively coupling to the lines. Vs is the desired signal source.
Since the device inside the green box inherently does not have balanced outputs, can balancing be achieved by using a potentiometer R2 on the diagram?
Did anybody use this scheme before? Im wondering whether is a proper method.
