Abstract
A current source apparatus for reducing interference with noise is provided. The current source apparatus includes a controllable current source and a feedback controller. The controllable current source provides an output current according to a control signal and produces a feedback signal according to the output of the controllable current source. The feedback controller is coupled to the controllable current source for receiving the feedback signal, and the feedback controller adjusts the control signal based on the feedback signal and outputs the control signal for controlling the controllable current source to output a stable output current.
