Claims
- 1. A computer graphics system comprising:
- a digital computer;
- a video memory connected to said digital computer and operable to store color codes for information in a video image; and
- a palette device connected to said video memory and including palette integrated circuity on an integrated circuit die, said palette integrated circuitry having:
- a dot clock buffer with transistors connected to supply rails and having an output distributed directly to the rest of the palette circuitry;
- an integrated circuit capacitor on the integrated circuit die of said palette device, the capacitor comprising a plurality of parallel-connected field effect transistors each having a source, a gate, and a drain, said gate of each of said parallel-connected field effect transistors is connected to a first common supply rail, and said source and said drain of each of said parallel-connected field effect transistors is connected to a second common supply rail, wherein said parallel-connected transistors are connected to form said capacitor having low resistance and high capacitance; and
- wherein said source or said drain of one parallel-connected field effect transistor is shared with another parallel-connected field effect transistor so as to form the source or drain of said other parallel-connected field effect transistor, and a first metal layer is disposed above said field effect transistors so as to interconnect the sources and drains of the parallel-connected field effect transistors and a second metal layer is disposed above said first metal layer so as to provide a connection from said first metal layer to said second common supply rail.
- 2. The computer graphics system of claim 1 further comprising a display device connected to said palette device.
- 3. The computer graphics system of claim 1 wherein said digital computer includes a host computer and a graphics processor connected to said host computer.
