Abstract
Disclosed are devices, systems and methods for allowing a ramp signal generator to reduce noise. A ramp signal generator may include a reference voltage generator configured to generate a reference voltage, a gain controller configured to control a gain of the reference voltage, a ramp signal controller configured to generate a ramp signal in response to an output signal of the gain controller, and an offset controller coupled to an output terminal of the gain controller in the form of a current mirror, and control an offset of the ramp signal in response to a control signal.
