Abstract

Power dissipation and delay product have emerged to be crucial issue, which prove to decrease the performance of microprocessor. The MOS current mode logic (MCML) is an evolving logic family that is attracting interest owing to its high speed operation, reliable performance in comparison to the CMOS logic family. However, the MCML suffers from constant static power dissipation, which, if left unmanaged, would result in an inordinate energy requirement in large scale ICs. In order to resolve this challenge, the newly introduced system designed a modified MOS current mode logic (modified MCML) that has remarkable characteristics of lesser power dissipation, better switching frequency and greater processing speed. With the aim of achieving low power dissipation, the dynamic MOS current mode logic (dynamic MCML) is proposed. Dynamic MCML circuits integrate the benefits of MCML circuits with those that of the dynamic logic families for achieving great performance using a low-supply voltage along with low-power dissipation. The results obtained from simulation show that the newly introduced design model of dynamic MCML yields greater power conservation and higher processing speed in comparison with conventional CMOS technology, MCML and modified MCML with regard to power dissipation and power delay product.
