DIGITAL-TO-ANALOG CONVERTER (DAC) WITH PARTIAL CONSTANT SWITCHING

摘要

Systems and methods are provided for digital-to-analog converter (DAC) with partial constant switching. A digital-to-analog converter (DAC) comprising a plurality of conversion elements may be configured to apply constant switching in only some of the conversion elements. Only conversion elements applying constant switching may incorporate circuitry for providing such the constant switching. Alternatively, each conversion element may incorporate constant switching circuitry and functionality, and the constant switching may then be turned on or off for each conversion element adaptively, such as based on input conditions.

1. A method for managing digital-to-analog conversions in a digital-to-analog converter (DAC), comprising:
determining switching characteristics for a plurality of conversion elements in the DAC, wherein each conversion element handles a particular bit in a digital input to the DAC; and configuring constant switching in said DAC based on determined switching characteristics, wherein said configuring comprises applying constant switching in only a subset of the plurality of conversion elements.
