Abstract: The design and experimental evaluation of a clocked adiabatic logic (GAL) is described in this paper. CAL is a dual-rail logic that operates from a single-phase AC power-clock supply. This new low-energy logic makes it possible to integrate all power control circuitry on the chip, resulting in better system efficiency, lower cost, and simpler power distribution. CAL can also be operated from a DC power supply in a nonenergy-recovery mode compatible with standard CMOS logic. In the adiabatic mode, the power-clock supply waveform is generated using an on-chip switching transistor and a small external inductor between the chip and a low-voltage DC supply. Circuit operation and performance are evaluated using a chain of inverters realized in a 1.2 /spl mu/m CMOS technology. Experimental results show that energy savings are achieved at clock frequencies up to about 40 MHz as compared to the nonadiabatic mode. Since CAL can operate both in adiabatic and nonadiabatic modes, power management strategies may be based upon switching between modes when necessary.
