Abstract

A dynamic flip flop is provided. The dynamic flip-flop comprises a transmission gate, a first inverter, a second inverter, a pull-up transistor and a pull-down transistor. The pull-up transistor and the pull-down transistor constitute a feedback inverter, and the feedback inverter is configured as a weak keeper circuit compared to the first inverter serving as a tri-state inverter. Therefore, the dynamic flip-flop can be such that makes a master latch to use the tri-state inverter for capturing data in order to reduce electric leakage. In addition, the dynamic flip-flop can also be such that makes a slave latch to use the weak keeper circuit for storing data, thereby avoiding floating point to drive the output.
