title: A low-noise preamplifier for nerve cuff electrodes.
abstract: A single-stage, low-noise preamplifier is designed using the concept of noise matching for recordings of neural signal with cuff electrodes. The signal-to-noise ratio is approximately 1.6 times higher than that of a low-noise integrated amplifier (AMP-01) for a cuff impedance of 1.5 komega. The bandwidth is 230 Hz-8.25 kHz (Rs=2 komega), and the common-mode-rejection-ratio is 91.2 dB at 1 kHz.
