Abstract
Mulitplying digital-to-analog converters (MDACs) are provided that reduce signal distortion without significantly raising current demand. These goals are achieved with input structures that lower input impedances and enhance the driving of nonlinear capacitances that are generally presented by the DAC portion of these devices.
