A current source whose current is proportional to absolute temperature is referred to as PTAT, and there are many such current sources to choose from. To get a dual slope current source, consider simply building two PTAT sources, one with each slope, and summing their outputs. The outputs should be scaled so that the cross over occurs at the desired temperature.
