Flip-flops (FF) typically consume more than 50% of random-logic power in an SoC chip, due to their redundant transition of internal nodes, when the input and the output are in the same state. Several low-power techniques have been proposed [1-5], but all of them incur transistor-count penalties, leading to an increase in size, which is too costly since(More)
A novel conditional clocking flip-flop is proposed. The flip-flop circuit does not consume any power when the data input of the flip-flop does not change its state. Taking the overhead of the auxiliary circuits into account, the flip-flop consumes less power than the conventional flip-flop when the data transition probability is less than 55%. By employing(More)
A low power pulse triggered ?ip?op (P-FF) design is done by the pulse generation control logic, an AND function, is removed from the critical path to facilitate a faster discharge operation. A simple two-transistor AND gate design is used to reduce the circuit complexity. A conditional pulse enhancement technique is devised to speed up the discharge along(More)
