Abstract
In an embodiment of the present invention, a feedback technique is used to track a reference signal with a DFE summing node common mode voltage. For example, in an embodiment implemented in CML, the feedback signal shifts both differential signals (e.g., the summing node common voltage and the reference voltage) by the same amount. In such an embodiment, the feedback technique preferably changes the reference common mode but not its differential mode.
