摘要

介绍了用于胸部多模式健康监测系统的PPG和PCG集成电路。利用斩波稳定技术和改进的噪声整形回路，降低了积分器中核心放大器的噪声和量化误差。PPG ROIC的DR为116.9dB，最大信噪比为92.7dB。此外，还介绍了用于区分PCG S1、S2峰的双峰检测器。该样机采用0.18 μm BCD工艺和多模式健康监测系统制作而成，可作为数字听诊器、心率监测仪和基于VTT的血压监测仪使用，并通过MATLAB编程实现。

Photoplethysmogram(PPG) and Phonocardiogram(PCG) integrated circuits for multi-mode health monitoring system on the chest

This paper presents PPG and PCG integrated circuits for multi-mode health monitoring system on the chest. Using chopper-stabilization technique and improved noise shaping loop, the noise of the core amplifier in the integrator and the quantization error are reduced in PPG ROIC. The PPG ROIC has a 116.9dB DR and achieves a maximum 92.7dB SNR. Also, Dual peak detector to distinguish PCG S1, S2 peak is introduced. The prototype is fabricated with 0.18 μm BCD process and multi-mode health monitoring system, can be operated as digital-stethoscope, heart-rate monitor, and VTT based BP monitor, implemented in MATLAB program.
