Zusammenfassung: | A digital-to-analog conversion circuit includes a first digital-to-analog converter (DAC) and a second DAC. The first DAC includes a first current generation circuit (CGC) and a first current-to-voltage converter. The first CGC generates a first current based on a first digital code received through a first terminal to provide the first current to an output node. The second DAC includes a second CGC and a second current-to-voltage converter. The second CGC generates a second current based on a second digital code received through a second input terminal to provide the second current to the output node. The first current-to-voltage converter and the second current-to-voltage converter convert a sum of the first current and the second current to a an analog voltage corresponding to a sum of the first digital code and the second digital code, and output the analog voltage at the output node. |
