    摘要: A complementary metal oxide semiconductor (CMOS) image sensor includes a photodiode, a switch and a comparator. The switch transfers a sensing signal to a sensing node from the photodiode. The comparator, which is directly connected to the sensing node, compares the sensing signal of the sensing node with a reference signal. The comparator outputs a signal corresponding to a voltage difference between the sensing signal and the reference signal.

    摘要: An ultrahigh speed bipolar transistor has a base region which is formed from a P.sup.+ base polysilicon sidewall using a self-alignment method, and a base junction window which is formed in order to minimize the collector-base junction capacity. In the method for fabricating this transistor, an insulation layer of oxide silicon or nitrogen silicon is formed under the base polysilicon layer. Accordingly, impurities from the base polysilicon layer do not diffuse into the epitaxial layer during the diffusion process. Instead, the extrinsic base region is formed by the diffusion of impurities from the polysilicon sidewall which is connected to the base polysilicon layer. Therefore the length of the entire base region is shortened. Furthermore, the junction area between the collector region is also lowered. Thus, the collector-base junction capacity is decreased and a higher operating speed is obtained.

    摘要: An apparatus for canceling a fixed pattern noise in a CMOS image sensor includes a storage device, a fixed pattern noise operation circuit, and a fixed pattern noise canceling circuit. The storage device stores first reference fixed pattern noises operated in a vertical blank section of an (n−1)th frame. The fixed pattern noise operation circuit calculates second reference fixed pattern noises based on the first reference fixed pattern noises stored in the storage device and blank fixed pattern noises output in a vertical blank section of an n-th frame and outputs the second reference fixed pattern noises to the storage device to update the first reference fixed pattern noises to the second reference fixed pattern noises. The fixed pattern noise canceling circuit cancels active fixed pattern noises in combination signals based on the combination signals output in an active section of an (n+1)th frame and including the active fixed pattern noises and pixel signals and the second reference fixed pattern noises output from the storage device.
