Abstract
In an embodiment, a current source having a piece-wise linear relationship between current and temperature is provided. The current source includes a first current source to provide current based on a first current-temperature relationship. The current source further includes a second current source coupled in parallel to the first current source. The second current source is to provide current based on a second current-temperature relationship. The current source further includes first mirroring circuitry to mirror a sum of the first current source and the second current source to an output current source. The current source also includes second mirroring circuitry to mirror the sum of the first current source and the second current source for comparison with a third current source. The third current source provides a minimum current magnitude and the third current source is coupled to the second current source to control output of the second current source.
