Abstract
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.
