ABSTRACT:
Systems and methods for reducing electrical noise generated during bus turnaround in signal transfer systems are provided. These systems include differential drivers having current sources continuously coupled to a signal bus during all operating modes of the drivers. A first transistor of the driver couples a first signal line of the bus to the driver current source and a second transistor of the driver couples a second signal line of the bus to the driver current source. Each transistor receives control signals in accordance with the operating mode of the driver. These control signals continuously and selectively couple the current source to the bus lines in a manner which provides uniform current distribution across the bus during all driver operating modes. The uniform current distribution across the bus minimizes interruptions in driver current dissipation and any effects from self-induced supply noise during signal transfers.
