Abstract: A summing node is provided for summing a first and second differential signals. Each of the first and second differential signals comprise respective direct and inverse signal components. The summing node comprises a first differential transistor pair comprising a first and second input and coupled to a first and second output. The summing node further comprises a second differential transistor pair comprising a third and fourth input and coupled to the first and second output. The first and fourth inputs are respectively coupled to the direct and inverse signal components of the first differential signal and the second and third inputs are respectively coupled to the direct and inverse signal components of the second differential signal.
