摘要:
A video digital/analog signal converter having a structure whereby the analog elements of the video D/A converter are separated from the digital elements of the video D/A converter and of arranging current cells of each of channels to one well. The present invention includes a Red-decoder group, a Green-decoder group, and a Blue-decoder group for decoding digital data of R, G, and B color channels, respectively, which are inputted in a state synchronized to R, G, and B clocks for controlling digital data of Red, Green, and Blue color channels. A plurality of data buses transfers digital data of R, G, and B color channel decoded at the R, G, and B decoder groups. First R, G, and B current cell matrixes generate current in response to digital data of the R, G, and B color data inputted from the data buses. Second R, G, and B current cell matrixes generates current in response to digital data of the R, G, and B color channel inputted through the data buses. The bias circuit transfers biases to the first R, G, and B current cell matrixes and the second R, G, and B current matrixes.
