[0039]另外,CM0S(Complementary Metal-Oxide-Semiconductor),中文学名为互补金属氧化物半导体,他本是计算机系统内一种重要的芯片,保存了系统引导最基本的资料。 [0039] Further, CM0S (Complementary Metal-Oxide-Semiconductor), the literature called complementary metal oxide semiconductor, He is an important system within a computer chip, the stored basic information system boot. CMOS的制造技术和一般计算机芯片没什么差别,主要是利用硅和锗这两种元素所做成的半导体,使其在CMOS上共存着带N(带-电)和P(带+电)级的半导体,这两个互补效应所产生的电流即可被处理芯片纪录和解读成影像。 CMOS manufacturing technology and general computer chips no difference, mainly using both silicon and germanium semiconductor elements made so on coexist with a CMOS N (with - e) and P (+ electrical tape) stage the semiconductor, which current is generated by two complementary effects can be interpreted as chip records and images. 后来发现CMOS经过加工也可以作为数码摄影中的图像传感器。 Later found after processing can be used as CMOS image sensors used in digital photography.

[0040]对于独立于电网的便携式应用而言,以低功耗特性而著称的CMOS技术具有一个明显的优势:CMOS图像传感器是针对5V和3.3V电源电压而设计的。 [0040] For the independent power portable applications, low power consumption CMOS technology, known for having a significant advantage: CMOS image sensor is for the 5V and 3.3V power supply voltage designs. 而CCD芯片则需要大约12V的电源电压,因此不得不采用一个电压转换器,从而导致功耗增加。 CCD chip and the power supply voltage of about 12V is required, and therefore had to use a voltage converter, thus increasing power consumption. 在总功耗方面,把控制和系统功能集成到CMOS传感器中将带来另一个好处:他去除了与其他半导体元件的所有外部连接线。 In terms of total power consumption, and the system control functions into CMOS sensor will be another advantage: He went all external cables and other semiconductor elements except. 其高功耗的驱动器如今已遭弃用,这是因为在芯片内部进行通信所消耗的能量要比通过PCB或衬底的外部实现方式低得多。 Its high-power drive Yizao now abandoned, because the energy consumed in the communication chip is much lower than that achieved by external PCB or substrate manner.

[0041 ] CMOS传感器也可细分为被动式像素传感器(Passive Pixel Sensor CMOS)与主动式像素传感器(Active Pixel Sensor CMOS)。 [0041] CMOS sensors may also be divided into a passive pixel sensor (Passive Pixel Sensor CMOS) active pixel sensor with (Active Pixel Sensor CMOS).

[OO42] 被动式像素传感器(Passive Pixel Sensor,简称PPS),又叫无源式像素传感器,他由一个反向偏置的光敏二极管和一个开关管构成。 [OO42], a passive pixel sensor (Passive Pixel Sensor, abbreviated PPS), also known as a passive pixel sensor, he is served by a reverse-biased photodiode and a switch configured. 光敏二极管本质上是一个由P型半导体和N型半导体组成的PN结,他可等效为一个反向偏置的二极管和一个MOS电容并联。 Is a P-type semiconductor and N type semiconductor PN junction of the photodiode essentially, he can be equivalent to a reverse-biased diode and a MOS capacitor in parallel. 当开关管开启时,光敏二极管与垂直的列线(Column bus)连通。 When the switch is turned on, the photodiode and the vertical column lines (Column bus) communication. 位于列线末端的电荷积分放大器读出电路(Charge integrating amplifier)保持列线电压为一常数,当光敏二极管存贝士的信号电荷被读出时,其电压被复位到列线电压水平,与此同时,与光信号成正比的电荷由电荷积分放大器转换为电荷输出。 Column lines located at the end of the charge integrating amplifier readout circuit (Charge integrating amplifier) ​​holding a column line voltage is constant, when the signal charges stored Beishi photodiode is read out, the voltage is reset to the voltage level of the column line, and this Meanwhile, the signal charges of the light is proportional to the charge integrating amplifier is converted by a charge output.

[0043] 主动式像素传感器(Active Pixel Sensor,简称APS),又叫有源式像素传感器。 [0043] The active pixel sensor (Active Pixel Sensor, referred to as APS), also known as active pixel sensor. 几乎在CMOS PPS像素结构发明的同时,人们很快认识到在像素内引入缓冲器或放大器可以改善像素的性能,在CMOS APS中每一像素内都有自己的放大器。 Almost at the same CMOS PPS pixel structure of the invention, it was soon recognized that the introduction of a buffer or amplifier can improve the performance of the pixel of the pixel in the CMOS APS pixel within each with its own amplifier. 集成在表面的放大晶体管减少了像素元件的有效表面积,降低了“封装密度”,使40%〜50%的入射光被反射。 Amplifying transistor integrated in the surface reduces the effective surface area of ​​the pixel element, reducing the "packing density", so that 40% ~ 50% of the incident light is reflected. 这种传感器的另一个问题是,如何使传感器的多通道放大器之间有较好的匹配,这可以通过降低残余水平的固定图形噪声较好地实现。 Another problem with such sensors is that a better match between how a multi-channel amplifier of the sensor, which can be preferably achieved by reducing the level of residual fixed pattern noise. 由于CMOS APS像素内的每个放大器仅在此读出期间被激发,所以CMOS APS的功耗比CXD图像传感器的还小。 Because each amplifier in the CMOS APS pixel is excited only during this readout, so that the power consumption of CMOS APS is smaller than the CXD image sensor.
