IP개요 | This paper presents a low-power active-based peak detector circuit for detecting R-wave in Electrocardiography (ECG). The proposed design uses a two-stage op-amp circuit to increase gain, bandwidth and to attenuate the noises obtained during acquisition of ECG signal from the electrodes. The two-stage op-amp circuit is designed using negative polarity technique with the amplification factor of 10 to achieve high gain and CMRR with low noise and less power consumption for biomedical applications. The design is implemented at 0.18μm CMOS technology using Cadence Spectre tool at the supply voltage of 0.9V. The proposed work would extend by designing the Read Only memory (ROM) and Digital to Analog circuit (DAC) circuit to store multiple ECG signal and frequency detection circuit to analyze heart beat variability. The main focus of this work is to design the timing adjustment circuit for irregular heartbeat. |
