Abstract :
An analog signal processor ASIC for ECG signals is presented. In addition to the power efficient extraction of ECG signals, it proposes an adaptive sampling scheme for data reduction, continuous-time electrode-tissue impedance monitoring for sensing motion artifacts, and band-power extraction for beat detection. The ASIC operates on a 2 V supply.
