1. A power-on reset (POR) circuitry comprising:
a comparator configured to compare a first voltage to a reference voltage based on a supply voltage, wherein the comparator is configured to output a POR trigger signal in dependence of a relation between the supply voltage and a target voltage level, wherein the comparator comprises a first output part configured to receive a balanced input, the first output part having a first component with a first resistance and a second component with a second resistance between the supply voltage and ground;
a trust unit comprising a second output part that is a replica of the first output part and is configured to receive an unbalanced input, the second output part having another first component and another second component between the supply voltage and ground, wherein the comparator and the trust unit are arranged in a common integrated circuit, and wherein the trust unit is configured to output a trust signal representing an indication whether the POR trigger signal is a trustable representation of the supply voltage reaching the target voltage level; and
a decision unit configured to receive the POR trigger signal and the trust signal and configured to output a POR signal in dependence of the POR trigger signal and the trust signal.
