Abstract
Input stages for use in multiplexing, and methods for using the same, are provided herein. An input stage includes an input terminal and an output terminal. A voltage input signal is accepted at the input terminal of the input stage. When the input stage is selected, a substantially unmodified version of the voltage input signal is presented at the output terminal of the input stage, when the input stage is selected. When the input stage is deselected, a rejection voltage signal is produced, where the rejection voltage signal is of substantially equal magnitude and opposite polarity to the corresponding voltage input signal in order to reject the voltage input signal and thereby present a substantially constant voltage at the output terminal of the input stage regardless of variations in the voltage input signal.
