DIGITAL-TO-ANALOG CONVERTER (DAC) WITH DIGITAL OFFSETS
Abstract:
Systems and methods are provided for digital-to-analog converter (DAC) with digital offsets. A digital offset may be applied to an input of a digital-to-analog converter (DAC), and digital-to-analog conversions are then applied via the DAC to the input with the digital offset. The digital offset is set to account for one or more conditions relating to inputs to the DAC, with the one or more conditions affect switching characteristics of one or more of a plurality of conversion elements in the DAC, and where each conversion element handles a particular bit in inputs to the DAC. The digital offset may be determined dynamically and adaptively, such as based on the input and/or conditions relating to the input. Alternatively, the digital offset may be pre-determined and fixed. One or more adjustments may be selectively applied to the digital offset for particular input conditions.
