Methods and apparatuses for generating a power-on-reset signal that is substantially independent of temperature change are disclosed. A reset circuit comprises a voltage generator, a first resistance element, a current generator, and a comparator. The voltage generator is configured for generating a first voltage signal having a negative temperature coefficient. The first resistance element is operably coupled between a supply voltage and a second voltage signal. The current generator is operably coupled to the second voltage signal and configured for sinking a reference current having a positive temperature coefficient and an offset current. The comparator is configured for comparing the first voltage signal to the second voltage signal to generate a reset signal. The present invention further includes semiconductor devices, semiconductor wafers, and electronic systems including the method or apparatus for generating the power-on-reset signal.
