Abstract
A monolithic integrated digital-to-analog converter is provided wherein the resistors are replaced by insulated-gate field-effect transistors thus avoiding any detrimental effects of variation between supposedly identical components. The equivalent resistance values of the insulated-gate field-effect transistors are determined by a fixed ratio of channel width to channel length.
