Abstract
A power voltage detector comprises voltage sensors for sensing supply voltages; and a logic. The logic combines the sensed supply voltages to generate a logic output indicative of whether the sensed supply voltages have met one or more predefined thresholds. Each of the voltage sensors has diode-connected transistors and passive resistance. The diode-connected transistors and the passive resistance are serially connected for generating an output, where the output is coupled to an input of the logic.
