Abstract: This paper presents the idea of analog amplifier which amplifies the amplitude of the real time EEG signals. This amplifier is for the front end application in brain signal measurement applications. In this paper instrumentation amplifier has been used for the designing purpose. The parameters of the proposed amplifier have been analyzed in order to achieve better gain and less power dissipation. The parameters like voltage, slew rate, gain bandwidth product, and sizing of Mosfet have been analyzed to achieve high gain using Cadence Virtuoso Software.
Index Terms: EEG, Opamp, Instrumentation Amplifier.
