Digital-to-Analog Converter |
摘要 |
A system for converting a digital signal to an analog signal is provided. The present invention provides a digital-to-analog converter (DAC) that can convert a large bit value digital signal to a corresponding analog signal. The digital-to-analog converter includes a bias regeneration circuit, and three sub-DACs. The bias regeneration circuit provides biasing to the three sub-DACs allowing the DAC to be implemented with smaller circuit area. In addition, the three sub-DACs may be digitally calibrated during the conversion process to increase the linearity of the DAC.
