Claim 0:
1. A ramp generator, comprising:
a ramp circuit configured to receive a first ramp enable signal from a control circuit during a first ramp period, the first ramp period including a first reset period and a first sensing period, and the ramp circuit being configured to output a first ramp signal to a correlated double sample (CDS) circuit;
an emphasis circuit configured to increase a voltage level of the first ramp signal during the first reset period, based on a first enable signal received from the control circuit; and
a pre-emphasis circuit configured to further increase the voltage level of the first ramp signal during a first pre-emphasis period in the first reset period, based on a second enable signal received from the control circuit.
