System and method for transition aware binary switching for digital-to-analog converters (DACs)

A system comprising:

• a multiplexer configured to
• output, at a first time, a first pair of a first digital value and a first dither value;
• receive, at a second time subsequent to the first time, a second pair of a second digital value and a second dither value;
• a controller coupled to the multiplexer and configured to:
• compare the first pair and the second pair;
• and
• control, based on a result of the comparing, the multiplexer to swap one or more bits of the second digital value with one or more bits of the second dither value, the swapped one or more bits of the second digital value being provided as an input to one or more digital-analog-converters (DACs).

A device comprising:

• circuitry coupled to a first plurality of digital-analog-converters (DACs) and configured to perform a dynamic element matching logic to output a unary code to the first plurality of DACs;
• a multiplexer coupled to a second plurality of DACs;
• and
• a controller coupled to the multiplexer and configured to:
• for a transition from a first pair of bits in first data provided to the second plurality of DACs to a second pair of bits in second data provided to the multiplexer,
• determine, based on the first pair of bits and the second pair of bits, whether the transition is of a first type or of a second type;
• in response to determining that the transition is of the first type, generate a first signal to control the multiplexer to output the second pair of bits to the one or more DACs;
• in response to determining that the transition is of the second type, determine whether the second pair of bits are to be swapped or not;
• and
• in response to determining that the second pair of bits are to be swapped, generate a second signal to control the multiplexer to swap the second pair of bits and output the swapped pair of bits to the one or more DACs,
• wherein data output by the multiplexer based on the second data has a predetermined number of bits that have binary values different from those of corresponding bits in the first data.
