Abstract
According to some embodiments, a reference voltage signal initially increases with increases in a processor voltage signal and then decreases with a further increase in the processor voltage signal. Moreover, according to some embodiments a comparator circuit generates a power indication signal when a substantially scaled processor voltage signal exceeds a reference voltage signal.
