Abstract
A tri-level digital-to-analog converter (DAC) element includes a first DAC cell. The first DAC cell includes a first reference circuit, a second reference circuit, and a switch circuit. The first reference circuit provides a first reference signal. The second reference circuit provides a second reference signal. The first switch circuit receives a control input from an input port of the tri-level DAC element, and controls interconnection between the first reference circuit, the second reference circuit, and an output port of the tri-level DAC element according to the control input. During a period in which the tri-level DAC element operates in a '0' state, the first switch circuit is arranged to couple at least one of the first reference circuit and the second reference circuit to the output port of the tri-level DAC element.
