ABSTRACT:
A low power pulse-triggered flip-flop comprises a latch containing a first conductive line and a first connection point and a pulse generator linking to the latch. The pulse generator includes a first N-transistor, a second N-transistor, a third N-transistor, a first inverter and a first P-transistor located on the first conductive line. The first N-transistor is connected to the first connection point and first conductive line. The second N-transistor and the third N-transistor are connected to the first conductive line, a second conductive line and a third conductive line. The first inverter is connected to the second conductive line. The present invention aims to reduce leakage power in a high level fabrication process, and can save power consumption and power-delay-product more than 17% over the conventional pulse triggered flip-flop, and also provides a smaller size of total transistors to lower average leakage current power consumption by 2.4 times.
