Abstract:
1. An integrated circuit comprising: a monitored region, the monitored region defined by three or more edges; and at least two temperature sensors for each of the three or more edges, the temperature sensors being arranged along the three or more edges such that each edge has substantially the same arrangement of temperature sensors; wherein positional information of a thermal characteristic of the monitored region is deter ruined by combining an output of at least a first one of the temperature sensors at a first position along a first one of the edges with an output of at least a second one of the temperature sensors at a second position along a second one of the edges, said positional information denoting a position other than the first and second positions; and wherein the position denoted by the positional information is not a position of any of the temperature sensors and is spaced a distance from each of the first and second positions which is greater than a distance between two adjacent ones of the temperature sensors arranged along a given one of the edges.
