A power-on reset (POR) circuit is provided. The POR circuit includes a first current source, a second current source, and a current comparator. The first current source is arranged to provide a relatively supply-independent circuit. The second current source is arranged to provide a supply-dependent current. The current comparator is arranged to compare the relatively supply-independent circuit with the relatively supply-dependent current to provide a POR signal.
