Abstract
One or more examples relate to methods and apparatuses for measuring a voltage node. An example method may include providing, between an input of a measurement circuit and a voltage node associated with a higher voltage domain than the measurement circuit, a circuit including decoupled capacitors, the decoupled capacitors including at least a first capacitor and a second capacitor; generating, by the measurement circuit, a first digital value representing a voltage level related to a voltage level at the voltage node at least partially responsive to performing a measurement process utilizing the circuit; and generating, by a processor, a second digital value representing the voltage level at the voltage node at least partially responsive to the first digital value and a scaling factor, the scaling factor representing a pre-specified relationship between the voltage level represented by the first digital value and the voltage level at the voltage node.
