A pixel cell readout circuit comprises a ramp generator having a ramp generator output. A first gain network is coupled to the ramp generator output and configured to provide a first variable comparator gain. A second gain network is coupled to the ramp generator output and configured to provide a second variable comparator gain. A first comparator has a first input coupled to the first gain network. The first comparator further has a second input selectively coupled to a first bitline and selectively coupled to a second bitline. A second comparator has a first input coupled to the second gain network. The second comparator further has a second input selectively coupled to the first bitline and selectively coupled to the second bitline.
