Abstract

This paper present a low-pass sigma delta modulator (LPSDM), which can be used for electroencephalogram (EEG) or electrocardiogram (ECG) signal acquisition systems. The LPSDM is implemented in continuous time Gm-C architecture and the systematic design flow is introduced. The power consumption of LPSDM is 1.614uW. According to the post-layout simulation under the bandwidth of ECG, a signal-to-noise and harmonic distortion ratio (SNDR) of 57.9 dB can be achieved.
