The article presents information on DAC output-amplifier. Semiconductor manufacturers undergoing technological innovations to meet the demands of system designers, who continue to demand increased functionality in less space. Many products use DACs to produce voltage references, enabling monitoring and control of the overall system. Designers are increasingly looking for higher-resolution DACs to allow fine tuning of the voltage levels. Package size is a key feature in determining product selection, so these devices should consume as little board area as possible. DAC makers are therefore presented with the challenge of increasing the converter's performance while simultaneously reducing its package size. A common approach to reduce IC size is to shrink process geometry. Process geometry usually refers to the gate length and determines the IC's voltage rating. Utilizing processes with smaller gate lengths can be useful for digital designs that are scalable, but designing mixed-signal products on smaller process geometries may not he optimal.
