A crucial and important part of a medical diagnostics system is the monitoring of the biopotential signals. These signals are recorded routinely in the modern clinical practice. Commonly, patients are connected to a bulky and mains-powered instrument, which reduces their mobility and creates discomfort. This limits the acquisition time, prevents the continuous monitoring of patients, and affects the diagnosis of the illness.
Biopotential readout circuits suffer from various problems for extracting biopotential signals. The extremely weak amplitudes of the biopotential signals makes them susceptible to various correlating signals. The circuits described in this book propose improved architectures and techniques for extracting high quality biopotential signals under low-power dissipation. Three different ASIC are implemented, each of which includes an improved IA and more functionality compared to its successor and compared to state-of-the-art.
