In this paper, a low power and low noise eight-channel analog front-end (AFE) IC for portable brain-heart monitoring applications is presented. The developed IC features a fully integrated eight-channel design which includes one channel for diffuse optical tomography (DOT), three channels for electrocardiography (ECG), and four channels for electroencephalography (EEG). In order to achieve the targets...
A low power consumption, high speed op-amp is designed for a 10-bit, 100 MSPS parallel pipeline A/D converter. The op-amp plays an important role in the ADC, because its conversion rate and power consumption are limited by the performance of the op-amps. The designed ADC in this paper employs parallel architecture based on double sampling technology, and shares the op-amp between the same stages of...
