Noise reduction techniques for programmable input/output circuits

Image Number 3 for United States Patent #6812869.

An input/output (I/O) circuit bank is disclosed, in accordance with one embodiment, having programmable I/O circuits configurable to support I/O interface standards for single-ended and differential signaling. The associated pads of one or more of the I/O circuits may be utilized to provide an external reference signal via a pass transistor onto an internal bus for use by the remainder of the I/O circuits. The pass transistors may be designed to function as lowpass filters to limit the amount of noise that passes through them.
