Abstract
A voltage-dependent impedance selector compensates for non-linearities that arise when the operating voltage of an electronic circuit changes. The voltage-dependent impedance selector includes a selection stage that selects a impedance based on the operating voltage of the electronic circuit. The selected impedance is connected to an output stage having a resistive value so that the selected impedance and the output stage form a voltage divider. The voltage-dependent impedance selector may, in some embodiments, be used in reference voltage generation or in impedance matching.
