Abstract
This description relates generally to piecewise temperature compensation. In an example, a circuit includes a knee code selector that can be configured to set a knee point temperature for a correction current responsive to a respective knee point temperature code of knee point temperature codes and a respective temperature sense signal of temperature sense signals. The circuit includes an output circuit that can be configured to provide the correction current responsive to the respective temperature sense signal and temperature voltages, and a trim digital to analog converter (DAC) that can be configured to provide a piecewise compensation current responsive to the correction current and a respective trim code of trim codes.
