Abstract:
After reviewing shortly why CMOS imaging sensors have taken an large part of the
imaging market initially held by CCD devices either for consumer or for industrial and
even scientific applications, this talk will present how CMOS imagers architectures
have evolved to allow for pixel size reduction, to reduce the noise and to increase the
readout rate while taking benefit from the possibility of integrating processing
functions. Additionally, the move to deep submicron technologies (DSM), required for
pixel size reduction or complexity increase, has introduced new challenges to keep and
even improve the sensitivity. State of art solutions allowing the DSM CMOS technology
to face with the imaging requirements will be described.
