Abstract

Providing a multiplexor outputting a reference voltage on unselected lines. A multiplexor that has at least one selected line and multiple unselected lines will have the unselected lines at a reference voltage. The selected line allows at least a portion of voltage to pass. Two gate circuits are used for each line, one that controls whether voltage (or a portion thereof) will pass, the other that connects the first gate circuit to a reference voltage, such as ground. In some embodiments the second gate circuit is always on, but is relatively small, such that the connection to the reference voltage has a weak effect on the output voltage. In other embodiments, the second gate circuit is only on when its associated first gate circuit is off.
