Todri-Sanial, "Synchronised 4-Phase Resonant Power Clock Supply for Energy Efficient Adiabatic Logic," 2017 IEEE International Conference on Rebooting Computing (ICRC), Washington, DC, USA, 2017, pp. 1-6, doi: 10.1109/ICRC.2017.8123661. Abstract: Adiabatic logic is an alternative architecture design style to reduce the power consumption of digital cores by using AC power supply instead of DC ones. The energy saving of the digital gates is strongly related to the efficiency of adiabatic AC power supplies. In this paper, we propose a resonant reversible power-clock supply design with four different phases. The resonance deviation between the four power-clock supplies is synchronized thanks to 12 control signals (3 controls signals per power-clock supply). We derive the energy dissipation of a 4-stage PFAL pipeline circuit supplied with the proposed resonant powerclock supply, which can dissipate up to 2.9 times less energy than a non-adiabatic CMOS pipeline.

Abstract: In this paper, we propose a LC resonator circuit using Hara's active inductor for adiabatic logic. The proposed circuit consists of four MOS-transistors Colpitts oscillator and an active inductor. This circuit require no inductor and can be produced two-phase sinusoidal clocking. From the simulation results, we show that the proposed circuit was operated as a 10 MHz, 3 V peak-to-peak LC resonant oscillator. Posted in #adiabatonauts

Current, "Clocked CMOS adiabatic logic with integrated single-phase power-clock supply," in IEEE Transactions on Very Large Scale Integration (VLSI) Systems, vol. 8, no. 4, pp. 460-463, Aug. 2000, doi: 10.1109/92.863629. 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.
