A Low-Power Low-Noise Open-loop Amplifier for Neural Recording



The signal path in a neural recording system must typically start with an amplifier in order to boost the signal levels and buffer the high source impedance. Because of the small signal amplitudes, amplifier noise must be minimized in order to avoid unnecessary degradation of the signal. Additionally, the high impedance of neural electrodes necessitates a high impedance input.
