| description | Disclosed is a device for detecting an electro-encephalogram (EEG) signal, comprising: an input unit to receive an EEG signal from an EGG signal detecting electrode attached to a human body, remove a noise component, and output the signal; an operation amplifier to modulate/demodulate and output the EEG signal from which the noise component is removed and inputted by the input unit by using a chopper stabilization method; a voltage converting unit which includes a feedback resistance and a feedback capacitor that are connected in parallel and which connects input terminals and output terminals of the operation amplifier; a feedback unit which includes a capacitor and connects an input terminal of either an anode or a cathode of the input unit and an output terminal of either an anode or a cathode of the operation amplifier; a low pass filter unit which includes a capacitor which is connected, in parallel, to the anode and cathode output terminals of the operation amplifier and is connected to output resistance of the output terminals of the operation amplifier to form a low band passing filter; and a non-inverting differential amplification circuit unit to receive the EEG signal outputted from the operation amplifier, remove a high frequency noise signal of a predetermined frequency band and output the EEG signal, thereby effectively removing the noise signal and obtaining the desired EGG signal only. |
