Abstract
A dual supply voltages converter divides a supply voltage by a constant to produce a feature voltage larger than one when the supply voltage is a first voltage and smaller than 1 when the supply voltage is a second voltage and squares the feature voltage for comparing with itself. After squared, a value larger than one will larger than itself and a value small than 1 will smaller than itself. As a result, the supply voltage is determined to be the first or second voltage and thereby to be converted to the desired output voltage.
