    摘要: In a CCD image sensor, a plurality of horizontal CCD registers are disposed adjacent to an image sensing area having matrix-arrayed image sensing cells and a plurality of vertical CCD registers. In the CCD image sensor, the channel impurity concentration of second horizontal CCD register, located away from the image sensing area, is more higher than that of first horizontal CCD register. With this feature, when the charges are transferred to the second horizontal CCD register across the first horizontal register, the residual charges in the first horiozntal CCD register are remarkably reduced.

    摘要: Circuitry to reduce signal noise characteristics in an image sensor. In an embodiment, a bit trace line segment is located between neighboring respective segments of a source follower power trace and an additional trace which is to remain at a first voltage level during a pixel cell readout time period. In another embodiment, for each such trace segment, a smallest separation between the trace segment and the respective neighboring other one of such trace segments is substantially equal to or less than some maximum length to provide for parasitic capacitance between the bit line trace and one or more other traces.

    摘要: An image sensor pixel includes a photosensitive region and pixel circuitry. The photosensitive region accumulates an image charge in response to light incident upon the image sensor. The pixel circuitry includes a transfer-storage transistor, a charge-storage area, an output transistor, and a floating diffusion region. The transfer-storage transistor is coupled between the photosensitive region and the charge-storage area. The output transistor has a channel coupled between the charge-storage area and the floating diffusion region and has a gate tied to a fixed voltage potential. The transfer-storage transistor causes the image charge to transfer from the photosensitive region to the charge-storage area and to transfer from the charge-storage area to the floating diffusion region.

    摘要: An apparatus for measuring the power frequency of a light source includes a photo-sensitive transistor, a modulators and a logic unit. The photo-sensitive transistor generates an electrical signal that is responsive to light incident thereon from the light source. The modulator generates a modulated signal based on the electrical signal that toggles at a rate substantially proportional to the power frequency of the light source. The logic unit is coupled to receive the modulated signal and determine its toggling frequency.
