Abstract
In accordance with an embodiment, a circuit includes: a replica input transistor, a first replica cascode transistor, an active current source, and an active cascode biasing circuit. The active current source is configured to set a current flowing through the first replica cascode transistor and the replica input transistor to a predetermined value by adjusting a voltage of a control node of the replica input transistor; and an active cascode biasing circuit including a first output coupled to the control node of the first replica cascode transistor, and the active cascode biasing circuit configured to set a drain voltage of the replica input transistor to a predetermined voltage by adjusting a voltage of the control node of the first replica cascode transistor.
