Abstract
One observation from the two neural amplifiers described in the previous two chapters is the dominance of flicker noise. Most of the existing power-noise optimization techniques target thermal noise. However, flicker noise is a significant concern for EMG/EEG/ECoG applications, where the bandwidth of interest is much lower (<500Hz) than that of neural applications (∼10kHz). Therefore, we will devote this chapter to discussing techniques to combat flicker noise.
