A Low Power Amplifier for Bio-Signal Processing
This paper presents a low voltage amplifier with low noise and very low frequency designed for bio-signal processing. 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 19 kHz. A SMIC 0.13μm CMOS process is used in design and simulation.
