Abstract
A circuit includes a first current source, a second current source, a third current source and a fourth current source. A load includes a first terminal connected to a first node between the first current source and the second current source and a second terminal connected to a second node between the third current source and the fourth current source. A bias control module includes a first output configured to output a first bias signal to the first and fourth current sources and a second output configured to provide a second bias signal to the second and third current sources. A capacitance is connected to the first and second outputs of the bias control module.
