Abstract :
An analog frame buffer suitable for early-vision processing is described. It has been fabricated using digital 1.6- mu m CMOS technology. A novel architecture is presented to compensate for the effect of parameter mismatch. The chip stores an image for a time frame of 1/30 s with an equivalent precision of more than 6 b. The array size is 32*32 and the cell dimension is 30.8 mu m*40 mu m. Power consumption is below 30 mW and the chip requires a bias supply of 5 V.
