Claim 0:
1. An image sensor comprising:
a first amplifier configured to compare a first voltage signal received from a first column line and a ramp signal and to amplify the first compared signal;
a second amplifier configured to amplify an output of the first amplifier;
a third amplifier configured to compare a second voltage signal received from a second column line and the ramp signal, and to amplify the second compared signal; and
a fourth amplifier configured to amplify an output of the third amplifier,
wherein the second amplifier and the fourth amplifier output a decision signal at different points in time by dummy switch control split,
wherein the dummy switch control split is based on dummy switch control signals that are different than an auto zero signal.
