In some embodiments, the invention includes a domino logic gate circuit having a domino state and a single ended domino compatible dual function generator. The domino state receives a domino stage input signal and provides a single ended intermediate signal as a function of the domino stage input signal, the intermediate signal having a state. The generator receives the intermediate signal and provides an out signal and an out* signal each having a state, wherein the out and out* signals have the same state during a precharge phase and have complementary states during an evaluate phase as a function of the state of the intermediate signal. In other embodiments, the invention includes domino logic gate circuit having a combined domino stage and dual function generator. The domino stage is to receive a domino stage input signal. The dual function generator is a single ended domino compatible dual function generator to provide an out signal and an out* signal that each have a state and during a precharge phase, the out signal and out* signal each have the same state, and during an evaluate phase the out and out* states are complementary states as a function of the domino stage input signal without a logic X circuit and a logic X* circuit.

A dual-rail static logic gate with a self cut-off mechanism is disclosed. In an embodiment, the output of the first rail is coupled to the input of the pull-up device of the second rail and vice versa. The cross-coupling allows the self cut-off mechanism of the static gate to function properly and provides for components which have lower capacitance than conventional static gates. The lower capacitance results in a faster static gate.

摘要:
A low loss on-die interconnect structure includes first and second differential signal lines on one of the metal layers of a microelectronic die. One or more traces may also be provided on another metal layer of the die that are non-parallel (e.g., orthogonal) to the differential signal lines. Because the traces are non-parallel, they provide a relatively high impedance return path for signals on the differential signal lines. Thus, a signal return path through the opposite differential line predominates for the signals on the differential lines. In one application, the low loss interconnect structure is used within an on-die salphasic clock distribution network.
