Integrated chip and method for forming integrated chip

Abstract

An integrated chip including a photodetector and a transfer transistor, a source follower transistor, a first overflow transistor, a first LOFIC (lateral overflow integration capacitor), a second overflow transistor, and a second LOFIC. The transfer transistor includes a first source / drain coupled to the photodetector. The source follower transistor includes a first source / drain coupled to a supply voltage terminal, a second source / drain coupled to an output terminal, and a gate coupled to a second source / drain of the transfer transistor. The first overflow transistor includes a first source / drain coupled to the gate of the source follower transistor. The first LOFIC includes a first electrode coupled to a second source / drain of the first overflow transistor. The second overflow transistor includes a first source / drain coupled to the gate of the source follower transistor. The second LOFIC includes a first electrode coupled to a second source / drain of the second overflow transistor.
