Power-gated MOS current mode logic (PG-MCML): a power aware DPA-resistant standard cell library

Paolo Ienne, Yusuf Leblebici, Francesco Regazzoni, Stéphane Badel

MOS Current Mode Logic (MCML) is one of the most promising logic style to counteract power analysis attacks. Unfortunately, the static power consumption of MCML standard cells is significantly higher compared to equivalent functions implemented using stati ...

Optimization of the wire grid size for differential routing: Analysis and impact on the power-delay-area tradeoff

Yusuf Leblebici, Stéphane Badel

In this paper, the impact of the wire grid size on the power-delay-area trade off of VLSI digital circuits with differential routing is analyzed. To this aim, the differential MOS current-mode logic (MCML) is adopted as reference logic style, and a complet ...

Tri-State Buffer/Bus Driver Circuits in MOS Current-Mode Logic

Yusuf Leblebici, Stéphane Badel

In this paper, two circuits are proposed to implement tri-state buffers/bus drivers for MOS Current-Mode Logic digital circuits. The first is a switch-based, fully differential circuit, while the second is a voltage follower-based, pseudodifferential circu ...

Breaking the Power-Delay Tradeoff: Design of Low-Power High-Speed MOS Current-Mode Logic Circuits Operating with Reduced Supply Voltage

Yusuf Leblebici, Stéphane Badel

In this paper, we study the operation of MOS current-mode logic (MCML) gates at lower-than-nominal supply voltages.We show that power can be traded for speed by reducing the supply voltage below the nominal value, while the power-delay product stays nearly ...
