    Abstract: A triangle shading method for a 3D graphic system includes the steps of (1) defining a starting position and two adjacent edges; (2) setting the tile containing the starting position as a target tile, then defining a target tile row; (3) checking if the lower boundary or upper boundary of the target tile crosses with the adjacent edges and pushing the address of crossing points into a stack if there exists such crossing points; (4) storing the associated data of the pixels of the target tile in memory; (5) checking if the target tile is the final tile of the target tile row, if not, setting the target tile to be the next tile of the current target tile and jumping to step (4); (6) checking if there are data remaining in the stack, if not, jumping to step (8); (7) popping a data from the stack, setting the data as a starting position and then jumping to step (2); (8) end.

    Abstract: The present invention discloses a current feedback operational amplifier, whose input ends are connected to a first amplifier which transmits an output to the gate terminals of at least one input pair of current switches, and the source terminal of one transistor of the input pair of current switches is connected to one of the input ends. Therefore, a negative feedback loop will be established by the first amplifier and the input pair of current switches. By means of the negative feedback loop, the input impedance, offset voltage and gain error are all reduced. The input impedance of the present invention is reduced as 1/1nullA times as the original one. Therefore, the aspect ratio of the transistors of the input pair of current switches is reduced.
