Abstract
A voltage comparator for comparing a reference voltage with a threshold, includes a first voltage-to-current converter to convert a reference voltage that determines the threshold into a reference current that depends on the reference voltage, a second voltage-to-current converter to convert the comparison voltage into a comparison current that depends on the comparison voltage, and an output stage to output a digital output level, wherein the digital output level depends on the reference current and the comparison current.
