ABSTRACT:
A method and structure for control of a rise time of a bus signal coupled to a driver circuit. A bus is coupled to the driver circuit and is operable to carry the bus signal. Voltage control elements are coupled to the driver circuit and the bus, and are operable to increase or decrease a voltage of the bus signal relative to a ground at one or more time instants. A control circuit coupled to the voltage control elements is operable to control the switching of the voltage control elements, thereby controlling the voltage level of the bus signal. Controlling a rise time of the bus signal of the driver circuit includes adaptively adjusting a voltage level of the bus signal relative to a ground at one or more discrete times by the use of the voltage control elements.
