Hello everybody
I need to compare zero voltage with a negative voltage , but comparators that are in papers do not work with zero and negative voltages , because their supply voltages are zero and vdd .
How can I find a comparator that has ability to compare zero and negative voltages ??
Please help me
Thanks
