It addition, CMOS (Complementary Metal-Oxide-Semiconductor), in
The entitled complementary metal oxide semiconductors (CMOS) of literature, he is originally a kind of important core in computer system
Sheet, saves the data that System guides is most basic.The manufacturing technology of CMOS and general computer
Chip does not has difference, the quasiconductor made mainly by silicon and germanium both elements, makes
It co-exists band N (band-electricity) and the quasiconductor of P (band+electricity) level on CMOS, this
Electric current produced by two complementary effects can be processed chip record and be interpreted to image.Later
Find that CMOS can also be as the imageing sensor in digital photography through processing.
For independent of the portable use of electrical network, famous with low power consumption characteristic
CMOS technology has an obvious advantage: cmos image sensor be for 5V and
3.3V supply voltage and design.CCD chip then needs the supply voltage of about 12V,
Therefore have to use an electric pressure converter, thus cause power consumption to increase.In terms of total power consumption,
Controlling to be integrated in cmos sensor with systemic-function to bring another benefit: he goes
Except all external connection lines with other semiconductor elements.The driver of its high power consumption is the most
Abandoned, this is because communicate consumed energy ratio at chip internal to pass through PCB
