A Micro-power Low-Noise Amplifier for Neural Recording Microsystems

This paper presents a low-noise and low-power amplifier, which can be used in frontend of the neural recording Microsystems. The proposed amplifier is one of the best powersizetradeoffs compared to the previous designs. By using of an active feedback configuration, midband gain is achievedwithout the large capacitor. The total capacitance of the architecture is only 3.8 pF. The midband gain is 40 dB, while passes signals from 1Hz to 10 kHz with an input-referred noiseof 5.2 μVrms and a power dissipation of 5.3μW. This neural amplifier is designed in a 0.5-μm 2P3M N-Well CMOS process
