Abstract
A device and method for enhancing current driving are provided. The device comprises an operational amplifier, a monitor device, and an auxiliary output device. The monitor device is adopted to monitor whether the non-inverse input signal is close to a maximum or minimum voltage of an input source of the operational amplifier. When the non-inverse input signal is close to the maximum or minimum voltage, the auxiliary output device outputs an auxiliary current to an output terminal of the device of enhancing current driving.
