一种改进的能量回收逻辑电路

An Improved Energy Recovery Logic Circuit

文章分析了能量回收电路的功耗组成,指出非绝热损失是能量回收电路的主要功耗能量来源,提出了一种改进的能量回收逻辑电路IERL。IERL电路增加了额外的回收路径,能够显著降低电路的非绝热损失,HSPICE模拟结果表明,IERL电路具有很好的低功耗性能。同时,给出了IERL电路的复杂逻辑门设计与级联方式,用0.8μmDPDM工艺实现了2位IERL全加器电路和两相正弦功率时钟电路。

The power consumption in energy recovery circuit is analyzed in this paper Results show that the nonadiabatic loss is the main source of power consumption Based on this fact, an improved energy recovery logic (IERL) structure is proposed IERL has additional recovery paths, and by improving the recovery percentage through the additional recovery path, it can reduce the nonadiabatic loss HSPICE simulation demonstrates that IERL circuit can greatly improve the low power performance Complex gate design and cascading of IERL circuits are also considered, which are easy to implement A 2bit full adder of IERL and a twophase sinusoidal power clock generator circuit were fabricated with 08 μm DPDM CMOS technology
