Abstract :
A subthreshold CMOS analog VLSI chip that, with a minimum of supporting circuitry, can smooth an image formed from a conventional video signal at the video frame rate is described. The chip was fabricated with 2-μm CMOS design rules, is approximately 5 mm by 7 mm in size, and contains a 46-by-47-node hexagonal resistive grid, sample-and-hold circuitry, and switching circuitry. Experimental performance results are reported
