Abstract
A ramp signal generator includes a resistor connected between an output node outputting a ramp signal that increases or decreases at a constant slope and a first power node which receives a first power voltage, and plural current cells. A cell current flows through each of the current cells to the first power node or the resistor. The current cells include a first current cell. The first current cell includes a first transistor connected between a first switching node and the output node, the cell current flowing to the resistor through the first transistor, a second transistor connected between the first switching node and the first power node, the cell current flowing to the first power node through the second transistor, and a negative feedback circuit that maintains a constant voltage at the first switching node.
