Low-Power Near-threshold MOS Current Mode Logic with Power-Gating Techniques

Abstract

Abstract-MOS Current-Mode Logic (MCML) is usually used for high-speed applications. However, the large static power dissipation of MCML circuit limits its application in portable devices. In this work, we proposed a power-gating (PG) technique to reduce the standby power of the near-threshold MCML. The PG 1-bit full adder and a mod-10 counter are designed and simulated using HSPICE at 45nm CMOS technology with predictive technology model (PTM) model. The simulation results show that the standby power of the PGadder and PG-counter is only 1.0nW and 3.0 nW, respectively. And the performance of the PG MCML circuits does not deteriorate.

Design of Filter Using MOS Current Mode Logic

“…Such a wide spread diffusion is mainly due to its robustness and the negligible static power consumption. There are the specific requirements which cannot be fulfilled by static CMOS [1][2][3][4][5].…”

“…MCML architecture provide higher immunity to supply noise due to their differential structure, lower cross talk due to the reduced output voltage swing and lower noise generated due to the constant current flowing through the supply rails. Power dissipation of MCML circuits is much larger than the conventional CMOS at low operating frequency [1][2][3][4][5].…”

“…It does not introduce the negative effect on robustness against power analysis attacks. The important goal of this method is minimizing the power, cost and battery life [2,3]. MCML Multiplier based algorithm is used to get the high performance circuit.…”
