This paper presents a low-voltage low-power low-noise amplifier suitable for neural recording applications. The amplifier is able to operate under a 1V supply by alleviating the tradeoff between the noise and the voltage headroom. The amplifier is based on a gm-cell, such that its effective transconductance is not a function of the bias current. As a result the noise contribution of the output transistors can be decreased without increasing the bias current. This bioamplifier rejects DC offset voltage using active low frequency suppression instead of AC coupling capacitors to achieve reduced-size and higher input impedance. The bioamplifier is designed for neural recording of action potentials and simulated in a 130 nm CMOS process. The amplifier consumes 5.2 μW from 1V supply voltage. The input referred noise is 4.7 μVrms‌‌. The amplifier has a Bandwidth (BW) from 110 Hz to 9.7 kHz.
