Abstract
A digital-to-analog (D/A) converter eliminates matching requirements and does not generate harmonics or noise. The D/A converter has an array of injectors for converting an input word to an analog voltage. A plurality of clocked switches discharge the injector array and the feedback path when switched into a first phase position and transfer the injector signal across the feedback path to the output of the D/A converter when switched to a second phase position. The conversion period, the time in which the digital input word is converted to an analog output voltage, is divided into N-1 subperiods. Each injector is enabled once or not at all for each subperiod such that the weighted signal injected during a single conversion period is constant and such that all the injectors in the array contribute an equal amount of signal during a conversion period.
