Abstract
A circuit including a power supply plane, a ground supply plane, and a signal source that generates reference voltage signals and a first signal. The signal source includes a driver adapted to generate a first signal to the receiver, the first signal having a present and a previous voltage levels. The signal source also includes a low reference voltage generator and a high reference voltage generator, each producing a low reference voltage signal and a high reference voltage signal, respectively, from a low reference output and a high reference output, respectively. The high reference output and the low reference output are coupled to the ground plane and the power supply plane, respectively. The high reference voltage generator and the low reference generator are capable of communicating the high reference voltage signal and the low reference voltage signal to the receiver.
