Low power low noise bio-amplifier with adjustable gain for digital bio-signals acquisition systems

Low Power Data Acquisition System for Bioimplantable Devices

“…Biopotential signals, such as electrooculogram (EOG), electroencephalogram (EEG), electromyogram (EMG), and electrocardiogram (ECG), cover a wide range of spectrum and signal bandwidth ranging from few hertz to 10 kHz [3] and the acquired signals through dense microelectrode arrays are very low in amplitude and susceptible to environment noises [4]. Proper processing of these signals requires amplification and noise cancellation, digitization, and digital signal processing before being considered for analysis.…”
