More Information
Summary:In the present invention, disclosed is an apparatus for removing the driving offset of an operational amplifier which includes a first boosting unit which is electrically connected to a positive terminal of the operational amplifier and boosts the potential of the positive terminal and a second boosting unit which is electrically connected to a negative terminal of the operational amplifier and boosts the potential of the negative terminal. The first boosting unit offsets a backward offset voltage by increasing the potential of the positive terminal when the backward offset voltage is generated between the positive terminal and the negative terminal. The second boosting unit offsets a forward offset voltage by increasing the potential of the negative terminal when the forward offset voltage is generated between the positive terminal and the negative terminal.
