High speed dynamic logic implementations have power consumption bottlenecks when driving large capacitive loads that occur in clock trees, memory bit/word lines and I/O pads. This severely limits their use in a System on Chip (SoC) at Gigabit rates. A novel dynamic logic gate that saves switching power by 50% with LC resonance is described. The stored energy on the load capacitance is transferred using an inductor during logic evaluation and recovered back for pre-charge, rather than being wasted. Implementation in a standard 90nm CMOS process illustrates feasibility with realistic on-chip inductors. Inductor values below 5nH are sufficient to operate at 1GHz speed driving 1pF of load while consuming less than 1.1mW of power from a 1.8V supply, thus breaking the f.CV2 barrier. The savings are realized over a wider range of frequency and less sensitive to LC variations than previously reported.
