Variations of the Power Dissipation in Adiabatic Logic Gates
نویسندگان
چکیده
The yield of adiabatic circuits strongly depends on the effects of parameter variations on the power dissipation. The dispersion of the threshold voltage has the most important impact on the yield. Different effects on the energy consumption due to interdie and intra-die variations of the threshold voltage are presented. Three logic families, the Efficient Charge Recovery Logic (ECRL), the Positive Feedback Adiabatic Logic (PFAL) and the 2N-2N2P are compared with respect to energy saving and operating frequency range. Finally it is shown that power dissipation variations due to parameter variations are strongly dependent on the logic family.
