Abstract
A system including is plurality of resistors, a plurality of comparators, and a decoder module. The resistors are connected in series between a supply voltage and a common voltage. A first input of each comparator is connected to a reference voltage. A second input of each comparator is respectively connected to one of a plurality of nodes between the resistors. The decoder module is configured to receive an output from each comparator and to output a plurality of bits based on the output of each comparator. Each of the plurality of bits indicates a different one of a plurality of voltage ranges. A present value of the supply voltage lies in one of the plurality of voltage ranges.
