摘要
全球对健康监测产品的需求正在增加。在用于个人健康监测应用的电路中，低功耗和低电压属性是需要解决的重要问题，以实现较长的电池寿命。本文设计了一种用于心电信号检测的生物医学放大器。该设计包括一个高通滤波器(HPF)、一个运算跨导放大器(OTA)、两个db线性变增益放大器、三个低通滤波器(LPF)和一个运算跨阻放大器(ORA)。特别是VGA和LPF使用了日志扩展技术。生物放大器从1v单电源中消耗的功率小于20muw。该电路采用0.18 μ m CMOS技术实现。
Design of Low-Power Low-Voltage Biomedical Amplifier for Electrocardiogram Signal Recording
The demand for health-monitoring products is increasing worldwide. Low-power and low-voltage attributes are important concerns that need to be addressed in circuits used for personal health-monitoring applications, to achieve a long battery life. In this paper, a biomedical amplifier is designed for electrocardiogram (ECG) signal detection. The design comprises of a high pass filter (HPF), an operational transconductance amplifier (OTA), two dB-linear variable gain amplifiers, three low pass filters (LPF), and an operational transresistance amplifier (ORA). In particular, the VGA and the LPF uses the log companding technique. The bio-amplifier consumes less than 20 muW of power from a 1 V single supply. The circuit is implemented in 0.18 mum CMOS technology.
