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 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.

摘要： A dynamic logic circuit incorporating reduced leakage state-retaining devices reduces power consumption of processors and other systems incorporating dynamic circuits. A keeper circuit provides a low leakage retention of the state of the output stage of the dynamic circuit so that an output circuit foot device can be disabled except when required for a transition in the output of the dynamic circuit. The keeper circuit includes a transistor having a smaller area than a corresponding transistor in the output circuit, thus reducing leakage through the gate of the output circuit when the keeper circuit is holding the output and the output circuit foot device is disabled. A self-clocked control of the output circuit foot device can be provided via a delayed version of the dynamic logic gate output, or may be provided by an external control circuit that generates a delayed version of the precharge clock or a multi-cycle signal.
摘要翻译：结合减少泄漏状态保持装置的动态逻辑电路降低了处理器和其他结合动态电路的系统的功耗。保持器电路提供动态电路的输出级的状态的低泄漏保持，使得输出电路脚装置可以被禁用，除非在动态电路的输出中需要转换。保持器电路包括具有比输出电路中的对应晶体管更小的面积的晶体管，从而当保持器电路保持输出并且输出电路脚器件被禁用时减小通过输出电路的栅极的泄漏。可以通过延迟版本的动态逻辑门输出来提供输出电路脚装置的自定时控制，或者可以由产生预充电时钟的延迟版本或多周期信号的外部控制电路提供。
