ABSTRACT:
Performance of a dual cascode voltage switch is improved and floating node effects including charge sharing and ratioing of output voltages are avoided by constituting the true and complement logic trees as pass gates of equal height, preferably limited, where possible, to a single transistor. The logic trees have substantially identical transistor layout configurations and different logic functions are established by selective connection of control and conduction terminals of the pass gates to reference logic level voltages of true and complement input variable signal values.
