摘要： A digital to analog converter (DAC) circuit to convert a digital input signal to an analog output signal, wherein the digital input signal comprises a plurality of Least Significant Bits (LSBs) and a plurality of Most Significant Bits (LSBs). The DAC circuit comprises a line decoder configured to receive the plurality of LSBs of the digital input signal and configured to generate line information based thereon. The DAC circuit further comprises a column decoder configured to receive the plurality of MSBs of the digital input signal and configured to generate column information based thereon. Further, the DAC circuit comprises one or more source cells arranged in a plurality of rows and a plurality of columns, wherein the one or more source cells are configured to be selectively activated and consequently generate an individual output signal based on the line information and the column information respectively.
