A circuit for reference current and voltage generation is provided. The circuit comprises a current bias circuit and a voltage reference circuit. Wherein, the current bias circuit receives an enable signal, provides a reference current, a bias signal and a startup signal when the enable signal is in an enabling state, and provides a first predetermined voltage and a second predetermined voltage when the enable signal is in a disabling state. The voltage reference circuit is electrically coupled to the current bias circuit. In addition, the voltage reference circuit enters into a turned-on state and provides a reference voltage after receiving the bias signal and the enable signal, and enters into a turned-off state after receiving the first and the second predetermined voltages.
