    摘要： The reduction of the power supply voltage of VLSI circuits to 3.3 volts results in a significant loss in input and output swing in traditional CMOS analog circuits. In order to achieve rail-to-rail operation, n-channel and p-channel MOSFETs are placed in parallel so that at least one type of transistors are operating in a high gain region throughout the entire input range. However, circuit characteristics change as transistors turn on and off. A constant transconductance bias means enables the rail-to-rail CMOS differential stage to possess a constant transconductance over the entire common mode voltage range. Significantly, the bias circuit does not require any matching between the transistors of opposite types.

    摘要： An area information generating unit generates plural pieces of area information each showing a partial area of a texture image. A polygon information generating unit generates polygon information including plural pieces of vertex information and an area ID. A rendering unit carries out interpolation on the texture coordinates of the vertices of a polygon on an output image to assign texture coordinates to each pixel located inside the polygon, and further acquires area information by referring to the area ID added to the polygon information and converts the texture coordinates assigned to each pixel of the output image in such a way that the texture coordinates fall within the area.

    摘要： In the present invention, an input assembly unit (1) receives vertex information used before and after geomorphing and index information as input, and uses the index information to output vertex information used before and after the geomorphing of each polygon. A polygon processing unit (3) interpolates vertex information that has been processed at a vertex processing unit (2) in accordance with the time in order to perform output for each polygon. A rasterizing unit (4) detects pixels included in each polygon output by the polygon processing unit (3) within the output image in order to output pixel information in which the vertex information for the polygon has been interpolated in accordance with the position of each pixel. A pixel processing unit (5) determines the color of each pixel of the corresponding output image using the pixel information.
