Abstract:
1. A pass-gate comprising: a field effect first pass transistor having at least a gate, source, drain, well and substrate, wherein an input signal is received at the drain or source and an output signal is presented at the source or drain, respectively; and second and third transistors having their respective drains functionally connected to the well of the first pass transistor, the gate of the second transistor functionally connected to the source of the first transistor, and the gate of the third transistor functionally connected to the drain of the first pass transistor; the source of the second transistor functionally connected to first cross coupled transistors, the first cross coupled transistors arranged to present to the source of the second transistor the higher of a power supply voltage or the signal voltage on the drain of the first pass transistor; and the source of the third transistor functionally connected to second cross coupled transistors, the second cross coupled transistors arranged to present to the source of the third transistor the higher of the positive potential or the signal voltage on the source of the first pass transistor.
