There are different types of neural amplifier recording and this paper will show two types of amplifiers. Both of them serve as Low noise and Low power amplifier but this paper will emphasize more on low noise. Since the human brain is so delicate, it is important that the neural amplifier must work perfectly and should not be affected by any other factors especially the noise. Therefore it is advisable to achieved input-referred noise as low as possible. This project will determine which designs can achieve low input-referred noise as a main objective. Then study on the current effect on the amplifier characteristic. And will also analyze of the amplifiers’ behavior on the temperature changes as human body temperature can change from time to time.
