Abstract: An m-of-n threshold gate is disclosed having an output stated derived from the voltage of a signal node. A “Go-to-Data” circuit pulls the signal node to a first state, corresponding to an ASSERTED (logically meaningful) output when a threshold number of inputs is in the ASSERTED state. A “Go-to-NULL” circuit pulls the signal node to a second state, corresponding to a NULL (logically meaningless) output when all inputs are in the NULL state. In a semi-dynamic embodiment, a weak feedback transistor holds the signal node in a predetermined state when some, but less than the threshold number of inputs is ASSERTED. In a dynamic embodiment, the signal node becomes isolated when less than the threshold number of inputs is ASSERTED, but holds sufficient charge to maintain the signal node in a state that existed at the time of isolation. A variety of GTN circuits are disclosed.
