MONOLITHIC INTEGRATED DIGITAL/ANALOG CONVERTER |
摘要 |
A monolithic integrated digital-to-analog converter makes use of rotating current-source control (dynamic element matching). After the conversion of a digital input signal into a code containing a sequence of first binary conditions corresponding to the numerical value of the input signal (so-called thermometer code), the bit switches of possibly same-sized current sources are rotatingly controlled in the sense of being selected, so that it becomes possible in the manufacture of the monolithic integrated digital-to-analog converters to balance out the manufacturing tolerances or process variations of the current sources. |
