A low clock load conditional flip-flop

We describe a low clock load conditional transmission-gate flip-flop aimed at reducing on-chip clock power consumption. It utilizes a scalable and simple leakage compensation technique, which injects additional leakage current in opposite direction, thus compensating for the worst-case leakage. During any low frequency operation, the flip-flop is configured as a static flip-flop with increased functional robustness. Post-layout simulations show a 30 % clock power reduction compared to a conventional static flip-flop.
