ABSTRACT:
A Universal Serial Bus (USB) switch matrix is provided. The switch matrix generally comprises a switch network, and amplifier, a adjustable current source, and variable resistors. The switch network is able to output a differential output signal and a common mode signal. The amplifier compares the common mode signal to a reference voltage, and the amplifier adjusts the magnitude of the current from the adjustable current source and the resistances of the variable resistors based at least in part on the comparison to adjust the peak-to-peak voltage swing of the output signal.
