A process-independent thermal protection circuit for microelectronic circuits is disclosed, including a thermal ramp generator suitable to generate a first thermal ramp signal and a second thermal ramp signal, a differentiator suitable to determine the difference between the first and second thermal ramp signals in order to generate a difference voltage signal, and a comparator suitable to compare the difference voltage signal with a reference voltage signal in order to assert a thermal protection signal when the difference voltage signal drops below the reference voltage signal.

[ What is claimed is:] [1.]1. A substantially process-independent thermal protection circuit for microelectronic circuits, comprising:a thermal ramp generator suitable to generate a first thermal ramp signal and a second thermal ramp signal, the first and second thermal ramp signals having different thermal effects;a differentiator suitable to determine the difference between said first and second thermal ramp signals and to generate a difference voltage signal based upon the difference; anda comparator suitable to compare said difference voltage signal with a reference voltage signal in order to assert a thermal protection signal when said difference voltage signal drops below said reference voltage signal, the asserted thermal protection signal indicating a temperature exceeding a predetermined temperature level.
