Abstract
A temperature-controlled counter/clock arrangement is provided where th rate or frequency of the counting is temperature dependent. This allows for a measuring of thermal accumulation and/or history. The temperature sensing is based upon the use of the varying current that will flow through a toward biased semiconductor diode. In one embodiment a constant voltage source is used so that the current variation will follow Arrhenius's law.
