Abstract
A current source for quickly adjusting an output current includes a constant current generation module, coupled to a control node, for generating a predefined current flowing through the control node in order to determine a voltage of the control node; a capacitor, coupled to an output terminal of the current source; a current variation detection module, coupled between the control node and the capacitor, for generating a variation on the voltage of the control node via the capacitor when the output terminal of the current source receives an instant current variation; and a trans-conductance amplifier, coupled between the control node and the output terminal, for changing a magnitude of the output current of the output terminal when the variation on the voltage of the control node is generated.
