A current source with adjustable temperature coefficient is provided. The current source uses a first current generation unit and a second current generation unit to respectively produce a positive temperature coefficient current and a negative temperature coefficient current. A current addition unit is used to add the positive and negative temperature coefficient currents, and compose the positive and negative temperature coefficient currents according to a predetermined proportion. Finally, a reference current of adjustable temperature coefficient and value is output.
