    • Speed, robustness and static performance of TSPC (True Single Phase Clocking) latches and flipflops are analysed in this paper. New latches and flipflops are proposed to upgrade the overall speed, power saving, clock slope insensitivity and static performance of TSPC. Both new single-rail and new dual-rail latches and flipflops are proposed. Among them are different dynamic, semi-static and fully-static versions. The delays are reduced by factors of 1.3, 2.1, 2.2 and 2.4 for the single-rail dynamic, the dual-rail dynamic, the semi-static and the fully-static versions respectively. In the same time, power consumptions are also reduced so the power-delay products are reduced by factors of 1.9, 3.5, 3.4 and 6.5 respectively for an average activity rate (0.25). These improvements are accompanied with less transistor counts and less clock loads. One unique type of the proposed latches uses only a single clocked transistor and only n-transistors in logic (in both n- and p-latches and in both dynamic and static versions).
    • 本文分析了TSPC(真正的单相时钟)锁存器和触发器的速度,鲁棒性和静态性能。 提出了新的锁存器和触发器来提升TSPC的总体速度,功耗,时钟边沿不敏感性和静态性能。 提出了新的单轨和新的双轨闩锁和触发器。 其中有不同的动态,半静态和全静态版本。 单轨动态,双轨动态,半静态和全静态版本的延迟分别为1.3,2.1,2.2和2.4。 同时,功率消耗也减少,因此功率延迟产品的平均活动率(0.25)分别降低了1.9,3.5,3.4和6.5倍。 这些改进伴随着更少的晶体管数量和更少的时钟负载。 提出的锁存器的一种独特类型仅使用单个时钟晶体管,并且仅使用n型晶体管(n型和p型锁存器以及动态和静态版本)。

    • A flip-flop circuit includes a charge injection module (500), a sense amp module (508), and a latch module (512).

The sense amp module (508) is configured to adjust a voltage of a second node (DZB) in response to detecting a voltage of the first node (D) crossing a threshold while the charge injection module (500) is providing the electrical charge to the first node (D). The latch module (512) is configured to, in response to the clock signal (CK), store a value based on a voltage of the second node (DZB). The latch module (512) is also configured to provide the value as an output (Q) of the flip-flop circuit.

    • An elastic pipelined latch. The latch includes a control input for configuring the latch into a repeater state or a latch state, a drive component responsive to the control input and for driving an input signal through as an output signal, and a pulse width/inhibit component coupled to the drive component. The latch further includes a reset threshold component coupled to the drive component for inhibiting oscillation of the drive component, and a latch component for passing the present state of the input signal to the output signal when configured as the repeater state and for maintaining the previous state of the output signal during transitions of a clock signal when configured as the latch state.

    • A differential cascode structure is configured to propagate a data state to a static latch at each active edge of a clock. A clock generator enables the communication of the data state and its inverse to the latch for a predetermined time interval. In a first embodiment, each cascode structure includes three gates (T1, T3, T5, T2, T4, T6) in series, the gates being controlled by the clock signal, a delayed inversion of the clock signal, and the data state or its inverse. In an alternative embodiment, each cascode structure includes two gates in series (T1, T3, T2, T4), the gates being controlled by the clock signal and the delayed inversion of the clock signal. In this alternative embodiment, each of these cascode structures is driven directly by the data signal or its inverse. The static latch obviates the need to precharge nodes within the device, thereby minimizing the power consumed by the device. The latch preferably comprises cross-coupled inverters, which, being driven by the differential cascode structure, enhance the switching speed.
    • 差分共源共栅结构被配置为在时钟的每个有效边沿处将数据状态传播到静态锁存器。 时钟发生器能够以预定时间间隔通信数据状态及其与锁存器的反相。 在第一实施例中,每个共源共栅结构包括串联的三个门(T1,T3,T5,T2,T4,T6),门由时钟信号控制,时钟信号的延迟反相以及数据状态或其 逆。 在替代实施例中,每个共源共栅结构包括两个串联的门(T1,T3,T2,T4),门由时钟信号和时钟信号的延迟反相控制。 在这个替代实施例中,这些共源共栅结构中的每一个直接由数据信号或其反相驱动。 静态锁存器消除了对设备内的节点进行预充电的需要,从而最小化设备消耗的功率。 闩锁优选地包括交叉耦合的反相器,其由差分共源共栅结构驱动,增强了开关速度。
