This paper aims at the problem that how to elimination the DC component of the MEMS geophone in the acquisition and processing of Seismic signal. Put forward to design a new circuit in the signal handing system. Design a new type of DC elimination circuit to eliminate the DC component through low-pass filter, reverse and other modules. The experiment result shows that, this new DC elimination circuit is easier to realize and has a large advantage than other existing DC elimination circuits.
