Abstract :
A new CMOS pixel which has lateral and vertical BJT structure is proposed. The structure is used for amplification in low light conditions. To reduce fixed pattern noise (FPN), correlated double sampling (CDS) is used. It has high responsivity compared with the conventional CMOS photodiode pixel and has advantages at low voltage condition so that it is suitable for the advanced CMOS process.
