In this paper, a method for designing CMOS DAC for video signal processing is described. The objective of the design is 8-bit resolution, and conversion speed more than 65 MHz. For the fast conversion, a new current cell is suggested. This cell improves glitch and output impedance. Employing the current cells in a 2-dimensional matrix structure, the DAC is constructed. SPICE simulations show faster settling time and reduced delay, adequate for 65MHz conversion.
