Design of a Low-Power Multiple-Valued Integrated Circuit Based on Dynamic Source-Coupled Logic
Akira Mochizuki, Takahiro Hanyu and Michitaka Kameyama

A new multiple-valued current-mode integrated circuit based on dynamic source-coupled logic is proposed for a low-power arithmetic- oriented VLSI processor. A judicious combination of source-coupled logic and dynamic logic makes it possible to reduce the power dissipation while maintaining a high-speed switching capability because the dynamic logic style makes steady current flow cut off. As a typical example of a high-performance arithmetic circuit, a radix-2 signed-digit full adder based on the dynamic source-coupled logic is implemented using a 0.18mm CMOS technology. Its power dissipation is reduced to about 70 percent in comparison with that of a corresponding binary CMOS implementation
