Abstract

Provided are methods and systems for performing binary data conversion in digital-to-analog converters (DACs) having sigma-delta modulators and involving data directed scrambling (DDS) algorithms to effectively shape the element mismatch errors to first-order shaped wideband noise. An example method may commence with receiving binary data, which comprises positive binary data and negative binary data. The method may further comprise converting, by a DDS unit, the binary data into binary thermometer code data. The conversion is performed by selectively assigning one or more logic ones in a data array from a current location of a positive (negative) pointer when positive (negative) binary data is received. A number of the one or more logic ones may be associated with the binary data. The method may further comprise circularly shifting the positive (negative) pointer to a new location within the array by the number of the one or more logic ones.
