Abstract
An analog gate configuration employing multiple input transistors, eliminates distortion in its output signal when switching between multiple input signals during a corresponding switch-over interval when the input transistors are sharing current, by providing circuitry for sensing the occurrence of the switch-over interval. The sensing circuitry modulates a current source during the switch-over interval to selectively increase the current to be shared by the input transistors such that the current through each input transistor is maintained constant for any transistor which contributes to the output signal.
