Abstract:
A ramp signal generator includes a reset control block suitable for generating a switch control signal according to a reset control signal from a control unit; a ramp signal generation block suitable for generating differential ramp signals, which include a power noise or a ground noise as well as a ramp noise; and a common noise canceling unit suitable for being initialized according to the switch control signal, and suitable for canceling common noise through a differential operation between the differential ramp signals.
