摘要

采用台积电0.18 μm CMOS工艺设计了2.4 GHz整数n频率合成器。本设计可用于IEEE 802.15.4a免授权超宽带医疗保健应用，如身体传感器网络与计算机网络进行无线连接。心电图是人体重要的生理参数。采用电荷泵线性化技术的电流开关差分科尔皮茨压控振荡器通过对心电的监测和分析，可以了解人体的健康状况，从而达到预防和诊断疾病的目的。本文提出了一种基于人体的离散时间采样保持复位环路滤波器的心电信号监测方案。

Frequency synthesizer with filter to signal detection for health care wireless network applications

A 2.4 GHz integer-N frequency synthesizer is purposed in tsmc 0.18-μm CMOS process. The purposed design can be used for the IEEE 802.15.4a unlicensed ultra-wideband healthcare applications such as body sensor network to wireless connect with computer network. Electrocardiogram (ECG) is the important physiological parameters in human body. Through monitoring and analyzing ECG, the current-switching differential Colpitts VCO by charge pump linearization technique can know the health condition of human body and achieve the purpose of prevention and diagnosis for diseases accordingly. In this paper, a solution of this design with a discrete-time sample-hold-reset loop filter build in human body for monitoring ECG signal detection is purposed.
