Abstract
A voltage comparator for detecting a voltage difference in a high-voltage domain, wherein said comparator receives an input voltage and compares it with a reference voltage also received in input, in which the output voltage from the comparator assumes the logic value 1 if the input voltage is greater than the reference voltage and assumes the logic value 0 if the input voltage is less than or equal to the reference voltage, wherein said comparator comprises low-voltage components and a single high-voltage component. In particular, the low-voltage components are MOS transistors and the high-voltage component is a high-voltage PMOS.
