It addition, CMOS (Complementary Metal-Oxide-Semiconductor), Chinese formal name used at school is complementary metal
Oxide semiconductor, he is originally a kind of important chip in computer system, saves the data that System guides is most basic.CMOS
Manufacturing technology and general computer chip do not have difference, partly led mainly by what silicon and germanium both elements made
Body so that it is co-exist band N (band-electricity) and the quasiconductor of P (band+electricity) level on CMOS, electricity produced by the two complementary effect
Stream can be processed chip record and be interpreted to image.Found that CMOS can also be as the figure in digital photography through processing later
As sensor.
For independent of the portable use of electrical network, the CMOS technology famous with low power consumption characteristic have one bright
Aobvious advantage: cmos image sensor designs for 5V and 3.3V supply voltage.CCD chip then needs about 12V
Supply voltage, therefore have to use an electric pressure converter, thus cause power consumption to increase.In terms of total power consumption, controlling
Be integrated in cmos sensor with systemic-function and will bring another benefit: he eliminate with other semiconductor elements all outside
Portion's connecting line.The driver of its high power consumption is abandoned the most, this is because communicate consumed energy at chip internal
More much lower than by the outside implementation of PCB or substrate.
Cmos sensor also can be subdivided into passive type element sensor (Passive Pixel Sensor CMOS) and active
Formula element sensor (Active Pixel Sensor CMOS).
Passive type element sensor (Passive Pixel Sensor is called for short PPS), is again passive type element sensor,
He is made up of a back-biased light sensitive diode and a switching tube.Light sensitive diode is substantially one is partly led by p-type
Body and the PN junction of N-type semiconductor composition, he can be equivalent to a back-biased diode and a mos capacitance parallel connection.When opening
When closing pipe unlatching, light sensitive diode connects with vertical alignment (Column bus).The charge integration being positioned at alignment end amplifies
Device reading circuit (Charge integrating amplifier) keeps column line voltage to be a constant, when light sensitive diode stores
Signal charge when being read, its voltage is reset to column line voltage level, meanwhile, the electric charge being directly proportional to optical signal by
Charge integration amplifier is converted to electric charge output.
Active pixel sensor (Active Pixel Sensor is called for short APS), is again active element sensor.Several
While CMOS PPS dot structure is invented, it is rapidly be recognized that introducing buffer or amplifier can change in pixel
The performance of kind pixel, has the amplifier of oneself in CMOS APS in each pixel.The amplification transistor being integrated in surface subtracts
Lack the effective surface area of pixel element, reduced " packaging density ", made the incident illumination of 40%～50% be reflected.This sensing
Another problem of device is, how to make to have between the multichannel amplifier of sensor preferably coupling, and this can be residual by reducing
The fixed pattern noise of remaining level preferably realizes.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.
