摘要：
A current mode analog signal multiplexor includes multiple input multiplexed differential amplifiers (12, 14), a reference amplifier ( 12.0, 14.0) and an output differential current amplifier (18, 20). An input multiplex control signal selects and enables one of the input multiplexed differential amplifiers for buffering and steering the input signal current to one side of the output differential current amplifier. The reference amplifier drives the other side of the output differential current amplifier. The output node of the output differential current amplifier remains at a substantially constant voltage potential while providing an output current which varies in relation to the selected input signal.
