description A ramp signal generating device and an image sensor for decreasing the latency of a ramp signal are provided. The ramp signal generating device may include a first circuit configured to detect a capacitance of a parasitic capacitor, a second circuit configured to charge the parasitic capacitor with a first voltage, and a third circuit configured to receive the capacitance as an input to generate a load current causing the ramp signal with a predetermined slope.
