Hello there!
I have been working over high-precision mixed-signal devices, and have seen this particular requirement fulfilled through both the methods with equal frequencies/occurrences. To be frank, I am still not very much clear about the differences between a bipolar supply (with a 0V ground) and a unipolar supply with a mid-point ground!
Why would anyone even consider the required overhead in generating a bipolar supply from a unipolar input? That increases the overall component count as well as the price of the system, and certainly does not helps with noise suppression and stability!
But still, I see a lot of systems developed with the same technique, even some of the portable devices and wearable gadgets.
I would be really grateful if someone could present a comparative analysis of the two methods of designing the power supply of a mixed-signal signal.
With best regards,
Abbas.
