Abstract
The present invention relates to a driving circuit used suitably for driving a capacitive load such as liquid crystal panel. The driving circuit of the present invention comprises a differential amplifying circuit, an output circuit and current control circuit. The output circuit is driven by an output signal of the differential amplifying circuit. A increased current signal is injected to the current control circuit for applying a positive feedback to increase an operating current of the differential amplifying circuit. A negative feedback for decreasing the increased current signal thus injected is also applied to the aforesaid current control circuit.
