A 30µW analog signal processor ASIC for biomedical signal monitoring KU Leuven
Power efficiency of readout circuits for ambulatory monitoring of biopotential signals has been significantly improved during recent years [1]-[3], leaving digital signal processing (DSP) and wireless transmission dominating the system power [4]. In addition, field tests have revealed that motion artifacts are a significant problem requiring even more processing power to differentiate between biological information and irrelevant motion ...
