Abstract
A voltage selection circuit includes: a power detection circuit configured to compare an output voltage with a first input voltage and a second input voltage, respectively; a latch circuit, coupled to the power detection circuit, and configured to flip respective logic states of a pair of output signals when the output voltage is lower than either the first input voltage or the second input voltage; and a selection circuit, coupled to the latch circuit, and configured to use either the first input voltage or the second input voltage as the output voltage based on the respective logic states of the pair of output signals.
