In addition, CMOS (ComplementaryMetal-Oxide-Semiconductor), Chinese formal name used at school is complementary metal oxide semiconductor, and he is originally a kind of important chip in computer system, saves the data that System guides is the most basic.Manufacturing technology and the general computer chip of CMOS do not have difference, mainly utilize the quartz conductor that silicon and this two kinds of elements of germanium are made, make it on CMOS, co-exist the quartz conductor of band N (band-electricity) and P (band+electricity) level, the electric current that these two complementary effects the produce chip that can be processed is noted down and is interpreted to image.Found that CMOS also can as the imageing sensor in digital photography through processing afterwards.
For the portable use independent of electrical network, the CMOS technology famous with low power consumption characteristic has an obvious advantage: cmos image sensor designs for 5V and 3.3V power line voltage.CCD chip then needs the power line voltage of about 12V, employing electric pressure converter of therefore having to, thus causes power consumption to increase.In total power consumption, another benefit will be brought in control and system function integration to cmos sensor: he eliminates all external connection lines with other semiconductor elements.Nowadays the actuator of its high power consumption is abandoned, this is because carry out communicating consumed energy than much lower by the outside implementation of PCB or substrate at chip internal.
Cmos sensor also can be subdivided into passive type element sensor (PassivePixelSensorCMOS) and active pixel sensor (ActivePixelSensorCMOS).
Passive type element sensor (PassivePixelSensor is called for short PPS), be again passive type element sensor, he is made up of a back-biased photodiode and a switching valve.Photodiode is a PN junction be made up of P-type semiconductor and N-type semiconductor in essence, and he can be equivalent to a back-biased diode and a mos capacitance parallel connection.When switching valve is opened, photodiode is communicated with vertical alignment (Columnbus).The charge integration amplifier sensing circuit (Chargeintegratingamplifier) being positioned at alignment end keeps column line voltage to be a constant, when the signal charge of photodiode storage is read out, its voltage is reset to column line voltage level, meanwhile, the electric charge be directly proportional to optical signal is converted to electric charge by charge integration amplifier and exports.
Active pixel sensor (ActivePixelSensor is called for short APS), is again active element sensor.Almost while the invention of CMOSPPS dot structure, people recognize very soon in pixel, to introduce the performance that energy disperser or amplifier can improve pixel, have the amplifier of oneself in CMOSAPS in each pixel.The amplifier transistor being integrated in surface decreases the effective surface area of pixel element, reduces " packaging density ", the incident light of 40% ~ 50% is reflected.Another problem of this sensor is, how to make there is good coupling between the multichannel amplifier of sensor, and this can be realized preferably by the fixed pattern noise reducing residual level.Because each amplifier in CMOSAPS pixel is only excited, so the power dissipation ratio ccd image sensor of CMOSAPS is also little during this reads.
