The simulation results show that the amplifier of improved control circuit not only solve the question of output DC offset, but also keep the voltage gain lowered by voltage compensation technique.
Due to its relative low amplitude properties, the bioelectricity signal is easy influenced by surrounding factor, the amplifier with low noise and voltageoffset is required.
