Abstract

Described are systems for producing differential logic signals. These systems can be adapted for use with different loads by programming one or more programmable elements. One embodiment includes a series of driver stages, the outputs of which are connected to one another. The driver stages turn on successively to provide increasingly powerful differential amplification. This progressive increase in amplification produces a corresponding progressive decrease in output resistance, which reduces the noise associated with signal reflection. The systems can be incorporated into programmable IOBs to enable PLDs to provide differential output signals.
