A 75dB-gain Low-power, Low-noise Amplifier for Low-frequency Bio-signal Recording

This paper presents a low voltage, low noise and very low frequency amplifier suitable for bio-signal recording. The amplifier requires only ± 0.6V supply and consumes 1.24µW, with a 75.5 dB gain over a bandwidth covering a range of frequencies from some hundreds of mHz to 19kHz. A UMC 0.13µm CMOS process is used in design and simulation. The new solution is suitable for a variety of biomedical applications.
