📋 论文概要

该论文提出一款电压可扩展的生物医学信号处理器，用于心电图（ECG）处理。通过在0.4V低电压下工作，实现了1MHz的时钟频率和13pJ/cycle的能量效率，解决了传统亚阈值设计工作频率低的问题。

💡 主要创新点

• 提出电压可扩展的架构，在亚阈值区域实现1MHz的工作频率，远高于传统kHz级频率。
• 针对ECG信号处理进行优化，在0.4V超低电压下达到13pJ/cycle的极低能量消耗。

While operating at the minimum energy point is attractive for energy-frugal devices like those used for wireless biomedical signal monitoring, the achieved clock frequency is usually in the kHz range. The low frequency combined with limited processing capacity, small on-chip memory, and low computation precision prevents the use of these systems for complex ambulatory monitoring beyond a simple ECG algorithm. Low-voltage systems with more computational power are demonstrated in [4] and [5]. In this paper, we present an event-driven system with resources to run applications with different degrees of complexity in an e
