A new circuit topology for a low voltage, low noise instrumentation amplifier (IA) applicable for magnetoencephalogram(MEG), magneto-oculogram, and magnetomyogram signal acquisition system is designed. The developed system from this research that consists of the small-sized MEG sensor, efficient methods of the compression and transmission of the measured MEG signals, will be used for the Bio-field signal measurement and analysis system. We present a monolithic low-power, low-noise analog front-end electroencephalogram acquisition system. It draws only 500 ㎂ from a standard 3-V battery, making it suitable for use in portable systems. Although fabricated in a standard CMOS technology, by using current feedback techniques it achieves a common mode rejection ratio of 120 ㏈ while the total input noise referred to input is kept below 1.5 ㎶ (rms).
