Zusammenfassung:A circuit for selecting a maximum supply voltage from a first voltage source and a second voltage source is disclosed. The circuit comprises a comparator for comparing the first voltage and the second voltage. Based on the comparison, a first bias signal and a second bias signal are generated for biasing the gate terminals of a first power switch and a second power switch respectively. The first power switch and the second power switch are biased such that the maximum voltage among the first voltage and the second voltage appear at an output node.
