智能手机基带处理器高速I/O电路的功耗优化设计与实现OA

From a circuit design perspective,this paper thoroughly analyzes the power consumption components of high-speed I/O circuits,identifying dynamic,static,and short-circuit power as the three primary sources.It clarifies how process nodes,signal integrity,and protocol overhead constrain power efficiency.To address these factors,the paper proposes a multi-level voltage-domain power delivery architecture tailored for advanced processes,a low-swing differential signaling optimization scheme,and a traffic-adaptive dynamic link management strategy.Experimental results demonstrate that the proposed scheme reduces total power consumption by 41.1％and improves single-bit energy efficiency by 41.1％under continuous high-speed transmission mode,while cutting standby power consumption by 86.2％.These improvements significantly enhance energy efficiency while ensuring signal quality meets communication reliability requirements.
