Specifically electrocardiography (ECG), electromyography (EMG) and single-unit neuron recording applications are discussed. These recording techniques sense electrical potentials generated by biological functions which are then amplified and sampled using electronic devices. The evolution of this biosignal monitor electronic device over four design genera- tions highlights the advantages of utilizing integrated circuits (ICs) designed solely for the given application. The final design combines the benefits of a low power IC and the highly customizable nature of a microconroller. Thanks to its high level of customizability after fabrication this system is ideal for innumerable applications in the field of biosignal moni- toring by lowering the technically barrier and development time required for many future biosignal monitoring applications.application/pdfen-USnoneElectrical engineeringElectrical engineeringThesis
