Abstract:
A ramp signal generator may include a ramp signal generation unit suitable for generating a ramp signal and a gain amplification control signal, an overlap voltage generation unit suitable for generating an overlap voltage to be overlapped with the ramp signal, and a voltage overlapping unit suitable for controlling a voltage gain by amplifying the ramp signal according to the gain amplification control signal, and overlapping the overlap voltage with the ramp signal.
