Abstract
Current output stages are provided. In accordance with an embodiment, a current output stage includes a voltage follower circuit, a first current mirror and a second current mirror. A node of the voltage follower circuit provides a voltage that follows a voltage at the output of the current output stage. An input of the first current mirror is connected (e.g., by a current path of a transistor) to the node of the voltage follower circuit that follows the voltage at the output of the current output stage. An output of the first current mirror is connected to an input of the second current mirror. An output of the second current mirror is connected to the input of the current output stage.
