This article presents a novel implementation scheme of the essential circuit blocks for high-performance, full-precision Booth multipliers leveraging a hybrid logic style. By exploiting the behavior of parasitic capacitance of MOSFETs, a carefully engineered design style is employed to reduce dynamic power dissipation while improving the glitch immunity of the circuit blocks. The circuit-level techniques along with the proposed signal-flow optimization scheme prevent the generation and propagation of spurious activities in both partial-product and adder-tree stages. Two full-precision Booth multipliers built from proposed strategies were compared to the state-of-the-art versions known from literature by means of extensive post-layout simulations in 65-nm CMOS technology. The proposed versions on average demonstrated up to 10% and 30% power savings in general.
