Abstract
Power supply detection circuit. The power supply detection circuit includes an input circuit responsive to a core power supply voltage to generate a first output voltage at a first node. The power supply detection circuit also includes a sense logic circuit to sense a voltage drop associated with the first output voltage, when the first output voltage is at a logic level HIGH. Further, the power supply detection circuit includes a current mirror circuit responsive to the voltage drop to increase voltage of the first output voltage to an input and output power supply voltage. Moreover, the power supply detection circuit also includes an output circuit that inverts the first output voltage to generate a second output voltage at a second node.
