Patent ID: 8610810

Claim:
A method for mitigating mismatch between signal chains in a complementary metal-oxide-semiconductor (CMOS) imaging system-on-chip (iSoC) sensor, comprising: selecting, by a first multiplexer, one of a first read bus or a second read bus from which to transfer a first sampled signal from a first two-by-two pixel structure to a first signal chain, wherein the first two-by-two pixel structure comprises a first set of four pixels that share a first common floating diffusion region; selecting, by a second multiplexer, one of the first read bus or the second read bus from which to transfer a second sampled signal from a second two-by-two pixel structure to a second signal chain, wherein the second two-by-two pixel structure comprises a second set of four pixels that share a second common floating diffusion region; and coordinating the selecting by the first multiplexer and the selecting by the second multiplexer to cause signal information from the first two-by-two pixel structure and the second two-by-two pixel structure corresponding to a same color plane to be transferred to a same signal chain.
