solution to stagnating energy efficiencies in digital integrated circuits, arising from slowed voltage scaling in nanometer CMOS [1-2]. The design of sequential elements for NTC, as well as in voltage-scaled systems operating at both near-threshold and super-threshold, has not been extensively studied. However, it is well known that sequential elements have a strong sensitivity to process variations in NTC [2], which can have a significant impact on system yield and power consumption. In order to achieve reliable energy-efficient operation across a wide operating voltage range, a flip-flop should have the following attributes: 1) static operation, since dynamic nodes are highly susceptible to PVT variations at low voltage; 2) contention-free transitions, since ratioed logic has poor robustness across the wide range of
