Abstract: In recent years, integrated circuits (ICs) for biosignal acquisitions have gained popularity in both academia and the industry due to the rising demands in medical applications. Biosignals such as brain signals monitored during electroencephalography (EEG) tests can have very low signal levels down to a few microvolts. Therefore, a biosignal measurement system usually requires multiple stages of amplification and filtering to extract the signal of interest from noise and interference. The need to improve the quality of the signal after processing in the analog front-end leads to...
