Extended range digital-to-analog conversion |
摘要 |
A conversion system converts an input signal from a digital signal to an analog signal over an extended dynamic range. The system includes a DAC system and a mode selector. The mode selector selects a mode of operation for the digital-to-analog converter system from a plurality of modes. The mode selector selects a mode according to a characteristic of the input signal. Each of the modes is associated with an instantaneous dynamic range and quantization noise level of the DAC system. The ensemble of modes provides an improvement in total or effective dynamic range compared to any single DAC component within the DAC system. |
