ABSTRACT:
A multi-device system and method for controlling voltage peaking of an output signal transmitted between input and output circuits of integrated circuit devices utilizes various electrical elements that can be adjusted after the fabrication of the integrated circuit devices to change the impedance of the input and output circuits. These adjustable electrical elements include one or more pass transistors in the input circuit whose on-resistances can be changed by adjusting a control signal supplied to the pass transistors. The adjustable electrical elements may also include one or more of the following: an adjustable current source, an adjustable resistor and a resistance-adjustable transistor operated as an adjustable resistor.
