Multiplexer to connect any of multiple input signals to an output path

A signal distributor comprising a first plurality of input ports and a second plurality of output ports, said signal distributor being operable to couple each input port of said first plurality of input ports to any one output port of said plurality of output ports, said signal distributor comprising:

• a third plurality of multiplexers, wherein a number of multiplexers in said third plurality of multiplexers equals a number of ports in said second plurality of ports,
• wherein each multiplexer in said third plurality of multiplexers has a fourth plurality of input nodes, with each input node coupled to a respective one of said plurality of input ports,
• wherein each multiplexer in said third plurality of multiplexers has one output node coupled to a corresponding one of said plurality of output ports,
• wherein each multiplexer comprises:
• a plurality of transistors, each transistor having a control terminal and a pair of current terminals, one terminal of the pair being coupled to a constant reference potential and the other terminal being coupled to an output node at one end of said output path,
• wherein the transistor is operable to provide a forwarded signal at said output node corresponding to a transistor-control signal if the transistor-control signal is received at said control terminal, and to tri-state said output node if said control terminal is coupled to a constant reference potential;
• a set of switches;
• and
• a control unit to receive a value indicating a specific transistor of said plurality of transistors which is to provide the corresponding input signal to said output path, said control unit to control the set of switches of the specific transistor to couple the corresponding input signal as said transistor-control signal at the control terminal of the specific transistor,
• said control unit controlling the set of switches of remaining ones of said plurality of transistors to provide said constant reference potential to the control terminal of each switch of the remaining ones of said plurality of transistors.
