A Low-Power Low-Distortion Amplifier for Fly Neural Recordings

摘要：

This paper presents the design and simulationof a low-power and low-distortion amplifier for flyneural recordings based on a gain boosted differentialoperational-transconductance amplifier (OTA). Theamplifier has been designed in a commercially available0.35 μm CMOS process. Powered by 1.5V, it consumes16.5 μ W and has a gain of 66+dBs and a bandwidth of 10KHz. Its gain and linearity are not sensitive to powersupply variations, making it suitable for feeding by apaper battery when recording brain neural signals frommoving flies.The designed amplifier is capable of driving a 10pF capacitive load therefore it can be directly connected to an oscilloscope or an ADC input.
