Circuit used for current with programmable temperature gradient. Disclosed is a current reference circuit which is configured to generate the reference current with the programmable temperature gradient. The current reference circuit comprises a resistor, a bandgap voltage circuit which is configured to generate bandgap voltage and to be coupled to the resistor, and a bias voltage circuit which is configured to generate bias voltage of variable polarities and to be coupled to the bandgap voltage circuit. The bandgap voltage circuit is configured to add the bias voltage of variable polarities to the bandgap voltage for generating the reference current passing through the resistor.
