Abstract
An on-chip temperature sensor for a semiconductor device. A temperature sensing mechanism includes a first current generator producing a first current that is proportional to absolute temperature of the semiconductor device. A second current generator produces a second current that is inversely proportional to absolute temperature of the semiconductor device. A current mode amplifier is coupled to amplifying the difference between the first current and the second current to produce a temperature signal.
