  • Publication number: 20060181626
    Abstract: Provided is an optical image receiving device having a high and rapid sensitivity and a wide dynamic range manufacture in a CMOS process. The image receiving device includes a capacitor transistor for a special purpose in addition to a general structure of three transistors and a light receiving portion. The capacitor transistor has first and second source/drain ports connected to the capacitance node and the floating diffusion node, respectively, and is gated in response to activation of a predetermined capacitor control signal. In the CMOS optical image receiving device, the floating diffusion node is pumped over an external power voltage. Thus, the electronic potential of the floating diffusion node in the initialization state is much higher than the maximum voltage of the light receiving portion. Thus, the CMOS active pixel has a very high sensitivity in a region where the intensity of light is weak.

  • Publication number: 20060139471
    Abstract: Provided is a CMOS active pixel and a driving method thereof. The timing of the transmission control signal and the reset control signal generated in the read-out section is performed in advance in the reset section. Thus, the potential wall between the photodiode area and the transmission transistor having a size corresponding to one generated in the read-to section is generated in the reset section in advance and the photodiode area is filled with charges. Thus, a dead region is reduced in the read-out section. Thus, a minimum light amount characteristic of an image sensor is improved. Also, in the reset section, the transmission transistor connecting the collection node to accumulate the signal charges generated from the photodiode and the floating diffusive node is turned on once or two time or more. Thus, a difference between the initial voltage of the collection node and the voltage of the reset level of the floating diffusive node is much reduced.

  • Patent number: 5039751
    Abstract: The polymers of ethylenically unsaturated monomers exhibit a greater degree of clarity and a greater degree of heat stability than do vinylidene chloride copolymers but do not have the barrier properties of vinylidene chloride copolymers. The present invention is an emulsion polymerized interpolymer, which provides both clarity and low oxygen permeability to applications where such properties are required of a polymer, having two miscible phases, which comprises (a) a first phase of an effective amount of at least one ethylenically unsaturated monomer and (b) a second phase of an effective amount of vinylidene chloride monomer and at least one ethylenically unsaturated comonomer wherein the first phase and the second phase are miscible.
