Abstract
Provided are devices having a ramp signal generator for adjusting a slope of a ramp signal by adjusting a current of a unit current circuit to adjust a step size. The ramp signal generator may include a unit current circuit including one or more current paths that allow a flow of an electrical current generated based on a ramp supply voltage, and a slope adjustment circuit configured to adjust a slope of a ramp signal by changing a current path of the electrical current flowing through the one or more current paths of the unit current circuit.
