Zusammenfassung:Some embodiments relate to an active pixel for use in a digital pixel sensor (DPS) imaging system having complete intra-pixel charge transfer functionality. The active pixel may include a first photodiode, and a first transfer gate and a second transfer gate each operatively coupled to the first photodiode. The first transfer gate and the second transfer gate may reside at opposite sides of the first photodiode. An electron drift current within the first photodiode may cause two direction charge transfer of charge of the first photodiode to the first transfer gate and the second transfer gate.
