This circuit is used to amplify low VLF signals with high to 250KHz and a large dc component. The gain of amplifier NE540L is 101, NE536T's Merits stream gain is 1, and it constitutes a part of low-pass network which can connect the DC input offset voltage to the inverting input terminal of the gain amplifier as common voltage, thereby suppressing the DC offset.
