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
Or the outside implementation of substrate is much lower.
Cmos sensor also can be subdivided into passive type element sensor (Passive Pixel
Sensor CMOS) and active pixel sensor (Active Pixel Sensor CMOS).

Amplifier is converted to electric charge output.
Active pixel sensor (Active Pixel Sensor is called for short APS), is named again active
Formula element sensor.Almost while CMOS PPS dot structure is invented, people are quickly
Recognize that introducing buffer or amplifier can improve the performance of pixel, at CMOS in pixel
APS has in each pixel the amplifier of oneself.The amplification transistor being integrated in surface reduces
The effective surface area of pixel element, reduces " packaging density ", makes 40%～50% enter
Penetrate light to be reflected.Another problem of this sensor is, how to make the multichannel of sensor put
Having preferably coupling between big device, this can be by reducing the fixed pattern noise of residual level relatively
Realize well.Quilt during only reading at this due to each amplifier in CMOS APS pixel
Excite, so the power dissipation ratio ccd image sensor of CMOS APS is the least.
