CA 2295814

A timing circuit, for use in an integrated circuit, generates relatively long time periods. The electrical properties (for example the resistance) of a pair of matched components are measured while heat is supplied to one of the components. When the values of the thermally dependent properties of the components differ by a certain amount, the timed period is over. The pair of matched components are located within thermally insulating structures within the IC.

Circuit de temporisation destiné à un circuit intégré et générant des périodes de temps relativement longues. Une mesure des propriétés électriques (par exemple de la résistance) de deux composants appariés est effectuée pendant qu'un des composants reçoit de la chaleur. Lorsque la différence entre les valeurs des propriétés dépendantes de la chaleur entre les composants atteint un certain niveau, la période de temporisation est écoulée. Les deux composants appariés sont disposés dans le CI, entourés de structures d'isolation thermique
