Abstract

A low power flip-flop is disclosed. The number of transistors which are coupled to the clock signal is reduced by more than half when compared with known flip-flop designs. The flip-flop comprises a pair of clocked transistors forming a pass gate and a plurality of inverters coupled thereto. By reducing the number of clock signal connections needed for reliable operation, the present invention reduces the power consumed by the flip-flop when operating at typical levels of activity by up to 70%.
