Résumé
Adiabatic logic is architecture design style which seems to be a good candidate to reduce the power consumption of digital cores. One key difference is that the power supply is also the clock signal. A lot of work on different adiabatic logic families has been done but the impact of the power supply and the power-clock network still remains to be studied. In this paper, we investigate the power-clock network effect on adiabatic energy dissipation. We derive closed-form analytical formulas to represent the output signal voltage and energy dissipation while taking into account the parasitic impedance of the power-clock network with respect to switching frequency such that adiabatic conditions are still met. Experiments, based on simulation, show that the power-clock network impacts both the energy efficiency of the circuit and its frequency.
