The double half-latch circuit is transparent to the state changes of the local input enable signal when the clock signal is low and opaque to state changes of the local input enable signal when the clock signal is high.He HuangMayur Joshi...
Gating of the latch and of the observation circuit may be implemented in many ways, and in which phase are clock voltages high, or low, depend on a variety of choices, many of which would be only peripheral to the embodiments of the present disclosure. The latch clock voltage 20′ maybe...
Low power toggle latch-based flip-flop including integrated clock gating logic Inventive aspects include integrated clock gating logic that can generate an internal glitch-free clock signal. Inventive aspects further include a toggle latch that is coupled to the integrated clock gating logic. The toggl...
The state retention power gating latch circuit may include multiple latches, each having a power input. In this case, an imbalance circuit is provided for each latch. Each imbalance circuit is operative to power down a corresponding latch while the power gate signal is asserted if the latch is...
Inventive aspects include integrated clock gating logic that can generate an internal glitch-free clock signal. Inventive aspects further include a toggle latch that is coupled to the integrated clock gating logic. The toggle latch can receive the internal clock signal from the integrated clock gating...
Another object of the present invention is to provide such an improved polarity hold latch which is free from race condition problems. A more specific object of the present invention is to provide a polarity hold latch having a set/reset capability at the lowest cost in additional circuit elemen...
