摘要： A dynamic logic gate has a device for charging a dynamic node during a pre-charge phase of a clock. A logic tree evaluates the dynamic node with a device during an evaluate phase of the clock. The dynamic node has a keeper circuit comprising an inverter with its input coupled to the dynamic node and its output coupled to the back gate of a dual gate PFET device. The source of the dual gate PFET is coupled to the power supply and its drain is coupled to the dynamic node forming a half latch. The front gate of the dual gate PFET is coupled to a logic circuit with a mode input and a logic input coupled back to a node sensing the state of the dynamic node. The mode input may be a slow mode to preserve dynamic node state or the clock delayed that turns ON the strong keeper after evaluation.

摘要： A dynamic logic gate has a dynamic node pre-charged in response to a pre-charge phase of a clock signal and a logic tree with a plurality of logic inputs for evaluating the dynamic node during an evaluate phase of the clock signal in response to a Boolean combination of the logic inputs. The logic tree has a stacked configuration with at least one multi-gate FEAT device for coupling an intermediate node of the logic tree to the dynamic node in response to a first logic input of the plurality of logic inputs or in response to the pre-charge phase of the clock signal. The multi-gate FEAT device has one gate coupled to the first logic input and a second gate coupled to a complement of the clock signal used to pre-charge the dynamic node.

摘要： A single-stage level shifting circuit is used to interface control signals across the boundary between voltage domains with differing positive or ground voltage potentials Asserted states are determined by the difference between the positive voltages potentials and the ground potentials. A lower positive power supply potential is not used to turn OFF PFET coupled to a higher positive power supply potential. Likewise a higher ground power supply potential is not used to turn OF NFETs coupled to a power domain where is significant ground shift. The single stage level shifting circuit has keeper devices that hold asserted states using voltages within the power gated domain.

摘要： A buffer, logic circuit, and data processing system employing fast turn-off drive circuitry for reducing leakage. Leakage current in logic circuitry is managed by coupling and decoupling the voltage potentials applied to large, high-leakage devices. Circuitry includes a low leakage logic path for holding logic states of an output after turning off high-leakage devices. A fast turn-off logic path in parallel with the low leakage logic path is used to assert each logic state in the forward direction from input to output. The large output device in each fast turn-off path is relieved of leakage stress by asserting logic states at driver inputs that cause the driver to turn OFF after the output logic state has been asserted.
