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