Abstract
A ramp signal generator includes a rising-edge current unit, a falling-edge current unit and a current-voltage converter. The rising-edge current unit provides a rising-edge output current that sequentially increases or decreases in synchronization with rising edges of a clock signal. The falling-edge current unit provides a falling-edge output current that sequentially increases or decreases in synchronization with falling edges of the clock signal. The current-voltage converter outputs a ramp voltage by converting a summed current of the rising-edge output current and the falling-edge output current.
