A CPL-based dual supply 32-bit ALU for sub 180 nm CMOS technologies
In this paper we present the design of a high performance 32-bit ALU for low power applications. We use dual power supply scheme and CPL logic for non-critical units of the ALU. In addition, latches with only n-MOS clocked transistors are used to interface logic operating at different power supplies and achieve static power free operation. Our simulation results indicate that, for the 180 nm-65 nm CMOS technologies it is possible to reduce the ALU total energy by 18%-24%, with minimal delay degradation. In addition, there is up to 22%-32% reduction in leakage power in the standby mode.
